Question

What is the number of edges of a pyramid, if the number of faces and vertices are 4 and 4 respectively ?
​

Answer 1

Answer :-

Euler's polyhedron formula, V−E+F=2

V = number of vertices = 4

V = number of vertices = 4E = number of edges =?

V = number of vertices = 4E = number of edges =?F = number of faces = 4

Thus 4−E+4=2

⇒E=8−2

⇒E=6

Number of edges = 6

Hope it will help you :)

Answer 2

Step-by-step explanation:

the answer will be 6

v-e+f = 2
