What does it cost us to build a house!
The exclamation point at the end of this sentence is only appropriate for a well-known song. It is synonymous with "very easy". And if the house is being built real, not song? From real bricks, real timber, real cement, which have a real price? Then the song exclamation mark will turn into a concerned question mark. And the emphasis will shift from the word "what" to the word "worth". And the costs that are hidden behind this word are determined not only by the building materials market, but also by our awareness in building matters.
Mathematics is an exact science, but bricks are different, and, therefore, their number in one cube is different. Therefore, to calculate how many bricks are in a masonry cube, you should take into account:
- brick size;
- type of masonry;
- the thickness of the seams.
Start counting by ticking these three unknowns. And to make sure that we can get several answers to one question about how many bricks are in a masonry cube, let's compare this number for different brick sizes.
Size, quantity in m3
1=512/394
1, 5=378/302
2=242/200
Note. The designation of the quantity is read as follows: “without masonry / taking into account masonry.”
Note that in the wording of the problem "how many bricks in a masonry cube", an inaccuracy was made, which will lead to confusion in the calculations. In fact, no one will build a brick cube in the truest sense of the word! A house, a garage, something else will be built, but not an ancient fortress, with walls a meter thick. The thickest masonry of the wall today is two and a half bricks. And there are two more, one and a half, one brick and half a brick. We will determine these values, then we will count, but not in cubes, but in square meters. Below are examples. But why then do you need to know how many bricks are in one cube of masonry, if the walls are measured in square meters? The logic is simple – build in m2, buy in m3. So how do you count? The algorithm is something like this:
1) find out the total area:
a) external walls;
b) interior walls;
2) determine the size of the brick and the type of seam in the masonry;
3) determine the masonry width:
a) external walls;
b) interior walls;
4) calculate the number of bricks separately:
a) for external walls;
b) for domestic;
5) output the total;
6) divide the resulting figure by the already known number of bricks in the cube;
7) with the result we go to the store - this is what we neednumber of brick cubes.
If you wish, you can add one more item - "multiply by the price of one cube" to know how much money to take. And you need to take with a margin for an additional 15% of the bricks that make up the battle and marriage. It has already been said above how many bricks are in a masonry cube. The following are some figures for a square meter. This is incomplete information, just for comparison, we will show how the number of bricks fluctuates depending on its size and taking into account / not taking into account the seam. When calculating, these nuances should be taken into account.
Example 1. For the same laying of 1 brick with different sizes:
Size - quantity (excluding/including seams)
1=128/102
1, 5=95/78
2=60/52
Example 2. For different masonry with the same brick size (1):
Type of masonry - quantity (excluding/including seams)
0, 5=61 /51
1=128 /102
1.5=189 /153
As you can see, the larger the size, the smaller the quantity, but the price will be higher. So the losses due to inaccurate calculations are significant. It is possible to minimize overcosts, not only by accurately calculating everything. If the laying is two and a half bricks, then broken bricks can also be used. There will be an overrun of the solution, but it is cheaper.
Everyone counted, but it's too early to put an end to it. For construction, wood is also required, or rather, materials made of wood. Beam, boards. So, it is necessary to calculate the amount of timber in the cube. Next tabledesigned to facilitate this process.

Explanation to the table: the numbers in brackets indicate the volume of one

Well, now you can sing the line with which the conversation started, not with an interrogative, but withexclamation point!
