Some bricks are arranged in an area measuring 20 cu. m. If the length, breadth and height of each brick is 25 cm, 12.5 cm and 8 cm respectively, then in that pile the number of bricks are (suppose there is no gap in between two bricks)
-
- 6,000
- 8,000
- 4,000
- 10,000
- 6,000
Correct Option: B
Volume of pile = 20 cu. metre
= 20 × (100)³ cu.cm.
Volume of one brick = (25 × 12.5 × 8) cu.cm.
| ∴ Required number of bricks = | = 8000 | |
| 25 × 12.5 × 8 |
