What is the volume of a rectangular prism with length 4 feet, width 2 feet, and height 3 feet?

• A. 8 ft^3
• B. 16 ft^3
• C. 24 ft^3
• D. 28 ft^3

Answer: (C)

The volume of a rectangular prism is found by multiplying its three dimensions: length, width, and height. Using the given measurements, 4 feet by 2 feet by 3 feet, you get 4 × 2 × 3 = 24. So the space inside the prism is 24 cubic feet. You can also see this by taking the base area (4 × 2 = 8 square feet) and multiplying by the height (3 feet) to get 8 × 3 = 24 cubic feet. The other numbers would come from using only two of the dimensions or a different height, which doesn’t match the given measurements, so they don’t represent the actual volume.
