6000 bricks ,each of dimensions 12 cm×5cm×7 cm, required to construct a wall 6 m long ,2.8 m high and 15 cm thick.

Step-by-step explanation:

Length of wall = 6 m = 600 cm

Breadth of wall = 2.8 m = 280 cm

Height of wall = 15 cm

Volume of wall = Length \times Breadth \times Height = 600 \times 280 \times 15 =2520000 cm^3

Length of brick =12 cm

Breadth of brick= 5 cm

Height of brick = 7 cm

Volume of brick =Length \times Breadth \times Height = 12 \times 5 \times 7 =420 cm^3

No. of bricks required =\frac{2520000}{420}=6000

Hence 6000 bricks ,each of dimensions 12 cm×5cm×7 cm, required to construct a wall 6 m long ,2.8 m high and 15 cm thick.
