Faces
The flat surface of a solid shape is its face. A solid shape can have '\(n\)' number of faces.
Example:
Let us consider a cube.

So, it is now understood that the number of faces of a cube is \(6\).
Edges
The line segment on a solid shape is called an edge.
Example:
Let us consider a cube.

Therefore, it is now understood that the number of edges in a cube is \(12\).
Vertices
The point where two or more edges join is a corner or vertex of a solid shape.
Example:
Let us consider a cube.

It is now understood that the number of vertices in a cube is \(8\).
