Which solid has six faces that are all squares?

Which solid has six faces that are all squares?

• A. Rectangular Prism
• B. Pyramid
• C. Cube
• D. Cylinder

Answer: (C)

Six faces that are all squares means every flat surface is a square and there are exactly six of them. The solid that fits this description is a cube. In a cube, each face is a square with four equal sides and four right angles, and all six faces are congruent. A rectangular prism also has six faces, but they are rectangles that may not be squares unless the box is itself a cube. A pyramid has triangular faces (and a base), not six square faces. A cylinder has curved sides and circular bases, not flat square faces. So the cube is the shape with six square faces.
