Which solid is a prism with six square faces?

• A. Cylinder
• B. Cube
• C. Pyramid
• D. Cone

Answer: (B)

Six square faces are exactly what a cube has. A cube can be thought of as a prism with square bases: the two opposite square faces act as the bases, and the other faces connect them as rectangles (in a cube those rectangles are also squares). The other shapes don’t have six square faces—one has curved surfaces and circular ends, another has a polygonal base with triangular sides, and another has a circular base with a curved side. So the solid described is the cube.
