Question

how many faces does a polyhedron have if it has 45 edge and 30 vertices . with proceedure

Answer 1

I think it's answer is 15

Answer 2

There are 17 faces in polyhedron.

Step-by-step explanation:

Since we have given that

Number of vertices = 30

Number of edges = 45

Let the number of faces be 'f'.

As we know that "Euler's formula " states that

$v-e+f=2\\\\30-45+f=2\\\\-15+f=2\\\\f=2+15\\\\f=17$

Hence, there are 17 faces in polyhedron.
