Question:

If the base of a right pyramid is square of side 12 cm and its volume is 1200 cm³, then its height will be -

Options:

25 cm

75 cm

28 cm

72 cm

Correct Answer:

25 cm

Explanation:

volume of pyramid = \(\frac{1}{3}\) area of base × height

⇒ 1200 = \(\frac{1}{3}\) × (12)² × h

⇒ \(\frac{1200}{4 × 12}\) = h

Therefore, h = 25 cm
