Step-by-step explanation:
Area of wall = 8×6×0.225 = 10.8 m²
Area of a brick = .25×.1125×.06 = .0016875 m²
n×Area of brick = Area of wall
n=Are of wall∕Area of brick
= 10.8/.0016875
= 6400

Answer:
6400 required
Step-by-step explanation:
Make metre into Centimeters
Volume of cuboidal Wall = L x B x H
= 800 x 600 x 22.5
= 1,08,00,000 cm^3
Volume of Cuboidal Brick = L x B x H
= 25 x 11.25 x 6
= 1687.5 cm^3
Number of Bricks Required = 1,08,00,000 ÷ 1687
= 6400 bricks
