A three-dimensional shape with six equal square faces.

A three-dimensional shape with six equal square faces.

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

Answer: (A)

Think of a cube as a three‑dimensional figure made of six equal square faces. This property—six congruent square faces—is what identifies it as a cube, with all edges the same length and faces meeting at right angles. The other shapes don’t fit: a sphere has no flat faces at all, a cylinder has curved surfaces plus circular bases, and a pyramid has triangular faces with a base (even a square-based pyramid) totaling five faces, not six squares. So the shape with six equal square faces is a cube.
