The volume of a prism is 960 cm³. If its base area is 80 cm², by what percentage should the height be increased to make the volume 1200 cm³?
Show answer & explanation
Correct answer: B
Explanation
Initial Height = 960 / 80 = 12
New Height = 1200 / 80 = 15
Increase = 15 − 12 = 3
Percentage Increase = (3 / 12) × 100 = 25%
