calculate the maximum volume or a rectangular prism whose surface area is 64m^2?

Answer 1

This would be a cube with each side being 4m in length.

All surface areas are equal in a cube and each = 4x4 m² = 16m²

There are 6 surface areas on a cube.

Then the total surface area = 16x6 = 96m²

and the total volume would be 4x4x4 = 64m³
