If the base of a right pyramid is square of side 12 cm and its volume is 1200 cm³, then its height will be -
Answer & explanation
Correct answer: option 1
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
