How many faces, edges and vertices does a pyramid have with n sided polygon as its base?
Answer :
Faces = n + 1,vertices = n + 1,edges = 2n
Explanation: in a pyramid ,the number of faces is 1 more than the number of sides of the polygon base i.e faces = n + 1
Also, the number of vertices is 1 more than the number of sides of the polygon base i.e. vertices = n + 1
Also the no of edges of pyramid is 2 times the no of sides of polygon
