Correct choices:
- The diagonal of the base is 4√5 centimeters.
- The area of a base is 40 square centimeters.
- The area of a lateral side between the bases is about 126.5 square centimeters.

Reasoning: Volume = base area × height, so base area = 800/20 = 40 cm². With square base side s, s² = 40 ⇒ s = 2√10. Diagonal = s√2 = 2√10 · √2 = √80 = 4√5. Lateral face area = side × height = 2√10 · 20 = 40√10 ≈ 126.49 ≈ 126.5. The prism is not a cube and the base side is not 20 cm.
