Which statement best describes a cube?

• A. A curved solid with two circular bases.
• B. It is a prism with six square faces.
• C. It has two circular bases.
• D. It has a curved surface and a single base.

Answer: (B)

A cube is a three-dimensional figure with six square faces, all meeting at right angles. Because it has six flat square faces and opposite faces that are parallel, it fits the description of a prism with six square faces. The other statements describe shapes with curved surfaces and circular bases (like a cylinder or a cone), which do not have six square faces. So describing a cube as a prism with six square faces best captures its defining features.
