Which solid is described as having six square faces and is a type of cube?

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

Answer: (C)

Think about how a solid is defined by its faces. A shape with six faces and every single face is a square is called a cube. Because all faces are squares and all the edges are the same length, the corners line up in a uniform way, giving a perfectly regular box-like figure. You can picture a standard die or a small boxed box to see this in real life. Other shapes have different kinds of faces: a cone has a circular base and a curved surface; a cylinder has two circular bases connected by a curved surface; a pyramid has a polygon base with triangular faces that meet at a point. None of these have six square faces, so they don’t match the description of a cube. Therefore, the solid described is the cube.
