How many faces does a cube have?
A. 4
B. 6
C. 8
D. None.

Hint: In this type of above question, we have to know about the property of a cube. So, we will draw a cube and then we will count the number of faces a cube can have.

Complete step-by-step solution -
We have been asked to find the number of faces a cube can have.
We know that a cube is a 3-dimensional figure. It has faces, edges and vertices. A standard die is an example of a cube.
Let us suppose a cube ABCDEFGH so that we can easily visualize its faces.

We can see the faces in the square form mentioned as follows:
Front face is ABCD.
Back face is EFGH.
Top face is ABFE.
Bottom face is CDHG.
Right face is BFGC.
Left face is AEHD.
So, there are a total 6 faces of a cube.
Therefore, the correct option is B.

Note: The six faces of a cube is easy to visualize if you consider an example of a die which is numbered from one to six. We can also use the net of a cube to visualize the faces of a cube. Just remember the point while counting the number of faces. Sometimes we just forget about top and bottom and we get incorrect answers i.e. 4.
