Concept:A cube is a three-dimensional solid with six identical faces, and each face is a square.
Explanation:A cube has all edges of equal length.
Every face is a flat, two-dimensional shape.
Since all sides of a face are equal in length and all angles are right angles, the shape is a square.
A rectangle has opposite sides equal but not all sides equal—so it is not correct.
Triangles and pentagons have fewer or more sides than a square.
Therefore, the only correct option is square.
Answer:Option C – Square
