A pyramid has a base of 9 cm side. If its height is increased by 50% and base remains same, by what percentage does volume increase?
Show answer & explanation
Correct answer: D
Explanation
Base side = 9 cm (constant), 50% increase in height
According to the formula:
Volume of the pyramid = Height
New height = 1.5h
Ratio of volumes = 1.5 : 1
Percentage increase = (1.5 − 1) × 100 = 50%
