Question

A wall of length 13.5 m ,width 60 cm and height 1.6m is to be constructed by using bricks , each of dimensions 22.5 cm by 12 cm by 8cm . How many bricks will be needed

Answer 1

Volume of Wall = lbh
=> V = (13.5 x 0.6 x 1.6) m^3
=> V = 12.96 m^3

Volume of Brick = (0.225 x 0.12 x 0.08) m^3
=> V = 0.00216 m^3

Now,

Number of bricks = Volume of wall/Volume of Bricks

=> No. of bricks = (12.96/0.00216)
=> No. of bricks = 6000
