To the question: A brick weighs a kilogram and half a brick. How much does a brick weigh? given by the author Alfiya the best answer is x - brick weight
0.5x - weighs half a brick
1+0.5x - brick weight (according to the terms of the question)
x=1+0.5x
x-0.5x=1
0.5x=1
x=2
brick weight 2kg - this is according to the task
in general - According to GOST, the weight of a standard red clay brick is 3.14 kilograms.
soooo! According to my formula, a brick is equal to 2 kg.!!!
Imagine that we put 2 kg of brick into one bowl! and on the other 1kg + half a kipich
at the same time, if a 2-kilogram brick is divided in half, it is 1 kg. accordingly, a 2-kilogram brick = 1 kg + half a brick that weighs 1 kg. everything works out.. and what’s not clear here....

Answer from Volatile[master]
boring ancient question is no longer interesting and not relevant
Answer from Yergey Kudelkin[guru]
Firstly, bricks are different. Usually it is 4kg.
1kg+(4:2)=3 THREEkg.
And in your case 2kg. The brick is wrong
Answer from Dima Titov[guru]
The condition of the problem is not entirely correct, but I also think your math skills are a little difficult. The brick weighs x. A half brick weighs 1/2x. and if so, then it is true that: 1+1/2x=x. It follows that this damn brick weighs 2 kg.
Regarding your comment to Ira Filonova: a brick weighs not a kilogram, but 1 kg plus half a brick, here half a brick is the “unknown” weight of the increase.
In general, it’s better not to ask such questions in this category, it doesn’t look much like science, it’s better to ask your deskmate, classmate or colleague (underline as appropriate :))
Answer from A.M. Efimov[guru]
Spit on the math and the crooked condition of the problem:
Place a brick on one pan of the scale. On the other we place a kilogram weight and half a brick.
Now let’s break the solid brick in half and remove half a brick from each cup of weight.
We get: on the left is half a brick, on the right is a kilogram weight
That is, half a brick weighs one kilogram
And two half-bricks, that is, intact, weigh two kilograms
Answer from Igor[guru]
Is half a brick half of the same brick that we are weighing or some other one?
If it’s different, you need to look at GOST.
And again the question is - how much does a brick weigh - a whole one or one from which half was torn off?
Answer from Nina Mincheva[guru]
2kg - in 1st grade they decide!
Answer from Jamara Sizova[guru]
Answer 4 kg
Answer from Dreamer[guru]
Just everything. You will tear your idea away from all the bricks))) These are just the conditions of the question. Look: we have 1kg data. half a brick and finally the brick itself. Imagine a scale on which a whole brick weighs on one bowl, and on the other a 1 kg weight and half a brick (of the same brand, of course). To find out the mass of a brick, it is convenient to create an equation with one unknown, let’s go back to the scales on one bowl, 1 kg and half, how to express it mathematically? Simple: 1+ 0.5x 1 is our kilogram which we know by convention, 0.5 x is half a brick, 0.5 is half, and we expressed the brick itself as X since its mass needs to be determined, therefore this is our unknown unknown . Since we have half of the unknown, it is expressed as 0.5 or 1/2. Next 1+0.5x=x we solve: 1=x-0.5x
1=0.5x
x=1/0.5
x=2
Answer: 2 kilograms.
The weight of the brick ranges from 1.6 to 6.6 kg. The value of this indicator is influenced by a number of factors: material of manufacture, purpose, size and shape.
Any construction is impossible without making preliminary calculations. A preliminary and important step is to determine required quantity building bricks. In addition, when building a house or extension, the load on the foundation should be taken into account. After all, incorrect calculations can lead to “subsidence” - the foundation simply will not support the weight of bricks and other materials. So how much does a brick weigh? Before answering this question, you should familiarize yourself with the varieties of this building material. Today we will also find out how much a pallet of bricks weighs, as well as the mass of a cube of this material.
Types of bricks
Depending on the material of manufacture, building bricks are:
- red (ceramic)
- silicate
Let's look at the features of each type and its main parameters.
How much does 1 red brick weigh?
The weight of the brick ranges from 1.6 to 6.6 kg.
Red brick is ideal for the construction of main and interior walls. This is a flattened rectangle, fired in a kiln, with the addition of various impurities. That's why brick walls in winter it retains heat well indoors, and in summer heat create coolness and comfort. The mass of a brick is determined by its size, density and purpose.
Red brick is divided by size into:
- single- the most “standard”, the parameters of which are 250x120x65 mm, and weight - from 1.8 to 4 kg
- one and a half– height 88 mm
- double– height 138 mm
Bricks are classified according to their purpose as follows:
- private– used for the construction of internal and external walls followed by plastering, therefore it has special “grooves” on the surface
- front (facing)– used in the construction of facades, arches
- fireproof (fireclay) brick - weighs from 3.6 to 3.8 kg. Due to its special properties, this material perfectly withstands high temperatures and “insensitive” to the effects of alkalis, acids, and radiation.
Ordinary and facing are:
- full-bodied– the overall structure of the element contains at least 13% voids. The weight of red solid brick is 3.6 - 4.5 kg, and the scope of application is foundation, load-bearing walls and other supporting structures.
- hollow– voids occupy approximately 20–45% of the structure of the product. This structural feature helps retain heat in the building, since an air layer is created inside each brick. Weight of one piece hollow brick– 2.5 kg.
Weight table for 1 red brick (in kg)
How much does a pallet of red brick weigh?
According to GOST, the weight of one pallet should be no more than 850 kg. To find out the weight of a pallet, you need only two indicators - the mass of one brick and the quantity on the pallet. In addition to the weight of the bricks, the total weight of the pallet includes the weight of the wooden container - from 30 to 40 kg.
Bricks on a pallet are usually laid out in the form of a cube, which is very compact and convenient for counting the amount of material. The weight of a brick cube depends on its size and purpose.
For example, 1 cube of solid single brick weighs 1693 - 1847 kg, and the mass of bricks on a pallet ranges from 660 to 1440 kg. The weight of one pallet of one-and-a-half bricks (for a similar purpose) will be 800 - 860 kg. Double size - the weight on the pallet is 1320 - 1440 kg, and the weight of a brick cube is from 1597 to 1742 kg.
How much does sand-lime brick weigh?
This type of building brick is used for laying load-bearing and front walls, partitions. The main advantage is high noise insulation and density. The mass of this type of material depends on its type.
Weight table for 1 sand-lime brick (in kg)
As you can see, the mass indicator is directly affected by the volume and density of the brick. One full-bodied sand-lime brick weighs about 3.7 kg, and one package fits about 200 - 380 pcs on a pallet. Consequently, the mass of the silicate tray will vary from 740 to 1410 kg.
How many single hollow bricks weighing 3.2 kg will fit on a pallet? For this you will need from 200 to 380 pcs. A cube of hollow brick weighs approximately 1640 kg, which is 513 pieces. If you need to calculate the weight of a pallet of double hollow bricks, then you need to know the weight of 1 brick (5.4 kg) and the number of pieces on the pallet (200). But in 1 cube about 242 hollow double bricks will fit, while the total weight of the cube will be 1305 kg.
Now we know how much a brick weighs different types, its weight on the pallet, as well as the mass of one cube of this building material.
The weight of a brick depends on the material from which it is made, its purpose, size and shape. The main characteristics of such a building material include size, water absorption, frost resistance, thermal conductivity and, of course, weight.
However, this does not mean that the heavier the material, the stronger or more durable it is. Bricks are produced from different types of raw materials and different ways. Firing is carried out at certain temperatures. The properties of the material that correspond to its purpose are considered paramount, and only then comes such an auxiliary characteristic as mass.
Weight of 1 red solid brick.
The standard option is red brick with dimensions 250x120x65 mm and weighing 4.3 kg. Weight of large format wall block can reach 24 kg, depending on the size of the brick - height, length and width.
The product can be divided into types:
- Based on the material, bricks are divided into two types: ceramic (red) and silicate.
- According to their purpose, bricks are divided into working bricks, facing bricks, clinker bricks and fireclay bricks.
- There are different sizes: single, one-and-a-half and double.
- Shape: solid or hollow (slotted).

In the table above you can find out the weight of m3 of brick, as well as the piece weight. All data is taken from GOST.
Weight of a solid brick.
Should be considered plump this material, which is made from refractory clay and has a minimum of voids inside. In percentage equivalent, this is 10 - 15% of the volume of bricks. The presence of voids makes the weight of such clinker greater than that of hollow clinker. This determines the targeted use of this stone.
Types of solid bricks.
- Ceramic. This type of production is made from clay or several types of clay. After the drying and firing procedure, the brick is porous and light; the presence of voids in it is not acceptable.
- Silicate. This material is made from a mixture of quicklime and sand. The output is a product that perfectly insulates sound in the room and has low thermal conductivity. Sand-lime brick has poor moisture resistance, so it is used for interior work.
- Hyper-pressed. From a mixture of quicklime, cement and special dye produce pressed bricks. After briquetting, the shape is perfectly flat, which suggests the use of the resulting material in construction for cladding surfaces.
To find out how much 1 solid brick weighs, you need to look at the table above. It indicates piece and m3 weight.
Standard brick weight 3.5 kg
The weight of the brick must be taken into account during its transportation and loading operations. Standard brick has dimensions 250x120x65 mm and weighs 3.5 kg. But this mass depends on many parameters and can differ significantly from the standard one.
Red brick weight
In everyday life, ceramic brick is called red. Its weight depends on its brand, the presence of voids, and shape.
Weight of solid (without voids) standard ceramic bricks(250x120x65 mm) - 3.4-3.8 kg.
The weight of a hollow (with voids) standard ceramic brick (250x120x65 mm) is 2.5 kg.
It is believed that the weight of a solid red brick 250x120x65 mm is 3.5 kg.
This construction material can be used for the construction of stoves and fireplaces, swimming pools, as it is resistant to water and high temperatures.
Since there are not only single bricks, but also one-and-a-half and double bricks, their weight is different. In addition, the weight varies depending on its classification (field of application). How much a red brick weighs can be found in the table.
| Red (ceramic) brick | |||

Sand-lime brick weight
Sand-lime brick is often called white because of its color. The weight of sand-lime brick differs from the weight of ceramic brick with the same dimensions. The scope of its application is quite diverse - the construction of load-bearing and internal walls, the construction of fences. Its use is not recommended in conditions high humidity and temperature.
