Which solid is defined as having six faces that are all squares?

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

Answer: (C)

Having six faces that are all squares identifies a cube. Each of the six faces is a square of the same size, and every edge where faces meet is the same length, with the faces meeting at right angles. That combination—six congruent square faces growing from a common center—defines a cube. Other shapes don’t fit this description: a cone has a circular base and a pointed tip with a curved surface; a cylinder has two circular bases plus a curved side; a sphere is perfectly round with no faces at all.
