Question

How many bricks will be required to construct a wall 13.5m ,6m,and 22.5cm thick if each bricks measure (27cm×12.5×9cm

Answer 1

Gn: Dimensions of wall = 13.5 m * 6 m * 22.5 cm = 1350 cm * 600 m * 22.5 m

      Dimensions of 1 brick = 27 cm * 12.5 cm * 9 cm

To find:

No. of bricks

no.of bricks = Volume of wall/ Volume of brick

                   = 1350 * 600 * 22.5 / 27 * 12.5 * 9

                   = 18225000 / 3037.5

                   = 6000

Therefore 6000 bricks are needed.
