Question

the dimensions of a brick are 24 cm × 12 cm × 8 cm. How many bricks will be required to build a wall 24 m long, 8 m high and 60 cm thick, if 10% of the wall is filled with mortar?

Answer 1

Volume of the wall = (2400 x 800 x 60)  

Volume of bricks   = 90%

of the volume of the wall  =[(90/100)*2400 *800 * 60]

Volume of 1 brick = (24 x 12 x 8)  

Number of bricks=(90/100)*(2400*800*60)/(24*12*8)=45000

Answer 2

hope this answer will help you.
