The base of a right pyramid is a square of side 40 cm long. If the volume of the pyramid is 8000 cm³, then its height is :
-
- 5 cm
- 10 cm
- 15 cm
- 20 cm
- 5 cm
Correct Option: C
Area of the base = 40 × 40 = 1600 sq.cm
We know,
| ∴ Volume of pyramid = | × area of base × height | |
| 3 |
| ⇒ 8000 = | × 1600 × h | |
| 3 |
| ⇒ h = | = 15 cm. | |
| 1600 |
