Question

how many faces vertices and edges are there in the following first a Prism whose base is a polygon of N sides 2nd a pyramid whose base is a polygon of N sides

Answer 1

In square pyramid
5 vetices,8 edges,5faces
In tiangular pyramid
4vertices,6edges,4faces
simply
base vertices+1 will give you faces and vertices
base sides×2 will give you edges

Answer 2

Answer:

1)

F = n+2

V=n*2

E =n*3

2)

F =n+1

V=n+1

E =n*2
