If the base of a right pyramid is rectangle of dimensions 15 cm x 8 cm and its volume is 720 cm², then its height will be?
Answer & explanation
Correct answer: option 4
volume = \(\frac{1}{3}\) Area of base × height
⇒ 720 = \(\frac{1}{3}\) × (lb) × height
⇒ 720 = \(\frac{1}{3}\) × 15 × 8 × height
⇒ \(\frac{720}{5 × 8}\) = height
height = 18 cm
