The base of a right prism is a trapezium. The length of the parallel sides are 8 cm and 14 cm and the distance between the parallel sides is 8 cm. If the volume of the prism is 1056 cm³, then the height of the prism is
-
- 44 cm
- 16.5 cm
- 12 cm
- 10.56 cm
- 44 cm
Correct Option: C
| Area of the base = | (sum of parallel sides) ×( per-pendicular distance) | |
| 2 |
| = | (14 + 8) × 8 = 88 sq.cm. | |
| 2 |
∴ Volume = Area of the base × height
⇒ 1056 = 88 × h
| → h = | = 12 cm | |
| 88 |
