Answer:
2000000 bricks
Step-by-step explanation:
The computation of the number of bricks to be used is shown below:
The Volume of brick is
= (15 × 8 × 5)cm^3
= 600 cm^3
And, the Volume of wall is
= (1500 × 1000 × 800)cm^3
= 1200000000 cm^3
Now Bricks needed is
= 1200000000 cm^3 ÷ 600cm^3
= 2000000 bricks
