What shape are the faces of a cube?
(A). Circle
(B). Triangle
(C).Square
Pentagon

Hint – A cube is a symmetrical three-dimensional shape, either solid or hollow, contained by six equal sides. To know the shape of the cube, draw the cube and observe the shape.

Complete step-by-step solution -
We have been asked about the shape of the faces of the cube.
We know a cube is a symmetrical three-dimensional shape, either solid or hollow, contained by six equal sides.
So, refer to the figure below,


So, the above figure shows a cube.
Here, ABCD, BCEF, EFGH, ADGH, ABEH, DCFG are the faces of the cube as shown in figure.
All these 6 faces have equal lengths of sides, so these are squares.
Hence, the correct option is C. Square.

Note- Whenever such types of questions appear, then refer to the figure of a cube. As mentioned in the solution, the figure shown above is a cube which has 6 faces and as we can see, the faces are of square shape.
