Answer:

1,250 bricks

Explanation:

Length of one brick = 20 cm

Breadth of one brick = 8 cm

Height of one brick = 6 cm

Volume of one brick = l × b × h

= 20 × 8 × 6

= 960 cm

Length of wall = 10 m = 1,000 cm

Breadth of wall = 6 cm

Height of wall = 2 m = 200 cm

Volume of wall = l × b × h

= 1000 × 6 × 200

= 12,00,000 cm

Number of bricks = Volume of wall/ Volume of one brick

= 12,00,000/ 960

= 1,250 bricks
