How many bricks of 22 centimetre x 10 centimetre x 7 centimetres are required to construct up a wall 33 metre long 3.5 metre high and 40 centimetre thick if cement and sand used in the construction occupy 110th the part of the wall

Question

How many bricks of 22 centimetre x 10 centimetre x 7 centimetres are required to construct up a wall 33 metre long 3.5 metre high and 40 centimetre thick if cement and sand used in the construction occupy 110th the part of the wall

Answer 1

In terms of bricks, the wall's dimensions are

3300/22 = 150
350/7 = 50
40/10 = 4

150*50*4 * .9 = 27000 bricks

That's just using raw volumes.

However, if we add 10% to each brick's volume, we only need 24545 bricks.

A more detailed analysis would add 3.23% to each dimension of the bricks, and then figure the whole number of bricks needed using the new larger size. I'll let you do that if you want.
