If the height of a right prism is increased by 60% while the base area remains the same, by what percentage does its volume increase?

1. 50%
2. 60%
3. 75%
4. 80%

Correct answer: 60%

Solution

For a prism, volume = base area × height. If the base area stays constant and height increases by 60%, the volume also increases by 60%.
