A godown is 15 m long and 12 m broad. The sum of the area of the floor and the ceiling is equal to the sum of areas of the four walls. The volume (in m³) of the godownis:
-
- 900
- 1200
- 1800
- 720
- 900
Correct Option: B
If the height of the godown be h metre, then
2(15 × 12) = 2 × h(15 + 12)
⇒ 27h = 15 × 12
| h = | = | metre | ||
| 27 | 3 |
| h = | = | metre | ||
| 27 | 3 |
