How many faces,

Question:

How many faces, edges and vertices does a pyramid have with n sided polygon as its base?

Solution:

In a pyramid, the number of vertices is 1 more than the number of sides of the polygon base, i.e. vertices = n + 1

Also, the number of faces is 1 more than the number of sides of the polygonal base, i.e. faces = n+ 1

But the number of edges is 2 times the number of sides of the polygonal base, i.e. edges = 2 n .
