A rectangular prism has length 3, width 2, height 5. What is its volume?

• A. 18
• B. 20
• C. 30
• D. 60

Answer: (C)

When finding the volume of a rectangular prism, multiply its length, width, and height. Here that’s 3 × 2 × 5, which equals 30. So the volume is 30 cubic units. The other numbers don’t use all three given dimensions, so they don’t match the actual product of length, width, and height.
