Question

how many bricks each of size 25 cm* 10 cm * 8 cm will be required to build a wall 5 cm long is 3 M high and 16 cm thick assuming that the volume of sand and cement used in the construction is negligible

Answer 1

Hope this will help u

Answer 2

12 bricks are required to build a wall.

Step-by-step explanation:

1 m = 100 cm

Length of brick = 25 cm = 0.25 m

Breadth of brick = 10 cm = 0.1 m

Height of brick = 8 cm = 0.08 m

Volume of brick = $Length \times Breadth \times Height = 0.25 \times 0.1 \times 0.08 =0.002 m^3$

Length of wall = 5 cm = 0.05 m

Breadth of wall = 3m

Height of wall = 16 cm = 0.16 m

Volume of wall = $Length \times Breadth \times Height = 0.05 \times 3 \times 0.16 =0.024 m^3$

No. of bricks required = $\frac{0.024}{0.002}=12$

Hence 12 bricks are required to build a wall.
