HELP PLEASE...​

Answer 1

Answer:

Volume of the wall ÷ Volume of a brick

Step-by-step explanation:

Answer

Volume of the wall =

6 m × 5 m × 0.5 m

30 m × 0.5 m

15 m³

1 m³ = 100 × 100 × 100 cm³ = 1000000 cm³

15 m³ = 1,50,00,000 cm³

Volume of a brick =

25 cm × 12.5 cm × 7.5 cm

2343.75 cm³

No. of bricks = 1,50,00,000 ÷ 2343.75

1,50,00,000 ÷ 2343.75 = 6400

6400 bricks are required to construct a wall of 6 m × 5 m × 0.5 m...
