Using euler’s formula (f + v = e + 2), find the number of edges. faces: 25 vertices: 17 edges: ?

This question is based on the concept of Euler’s Formula. Therefore, there are 40 edges.

Given:

Faces: 25 Vertices: 17

We need to determined the number of edges by using the  Euler’s Formula (F + V = E + 2).

According to the question,

It is given that,

Faces: 25

Vertices: 17

By using Euler’s Formula ,

F + V = E + 2

Now put all the given values in the formula.

We get,

25 + 17 = E + 2

42 = E + 2

42 - 2 = E

E = 40

Therefore, there are 40 edges.
