Answer 2

12500 bricks are required to make a wall

Step-by-step explanation:

Length of brick = 20 cm

Breadth of brick = 5 cm

Height of brick = 5 cm

Volume of brick = $Length \times Height \times Breadth$

Volume of brick = $20 \times 5 \times 5$

Volume of brick =$500 cm^3$

Length of wall = 2.5 m = 250 cm

Breadth of wall =0.5 m = 50 cm

Height of wall = 5 m = 500 cm

Volume of wall =$Length \times Breadth \times Height = 250 \times 50 \times 500 =6250000 cm^3$

No. of bricks are required =$\frac{6250000}{500}=12500$

Hence 12500 bricks are required to make a wall
