Answer 1

Answer:

Therefore, the no. of bricks required to build a wall 5 m long, 3 m high and 30 cm thick are 20 + 24 + 4 = 24 + 24 = 48 bricks. ans/-

Step-by-step explanation:

Here you go..............

Length of a brick = 25 cm

Length of the wall = 5 m = 500 cm

No. of bricks = 500/25

= 20

Height a brick = 12.5 cm

Height of the wall = 3 m = 300 cm

No. of bricks = 300/12.5

= 24

Breadth of a brick = 7.5 cm

Breadth of the wall = 30 cm

No. of bricks = 30/7.5

= 4
