A rectangular prism with length 4, width 3, height 5 has volume equal to which value?

A rectangular prism with length 4, width 3, height 5 has volume equal to which value?

• A. 60
• B. 40
• C. 20
• D. 15

Answer: (A)

Volume is found by multiplying all three dimensions: length, width, and height. With 4, 3, and 5, you do 4 × 3 × 5. Multiply 4 by 3 to get 12, then multiply by 5 to get 60. So the rectangular prism’s volume is 60 cubic units. This number uses all three measurements, unlike the two-dimensional products 4 × 5 = 20 or 3 × 5 = 15, which explain why the full three-dimensional product is the correct value.
