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.
