A right rectangular prism with square bases has a height of 20 centimeters and a volume of 800 cubic centimeters. Which statements describe the prism? Choose three correct answers.

The base area is volume divided by height: 800 ÷ 20 = 40 square centimeters, so B is correct. Since the base is square, each side is √40 = 2√10 centimeters; the prism is not a cube, and the side is not 20 centimeters. A lateral side has area 20 × √40 = 40√10 ≈ 126.5 square centimeters, so C is correct. The base diagonal is √(40 + 40) = √80 = 4√5 centimeters, so E is correct.
