Question

A Polyhedron has 60 edges and 40 vertices. Find the number of faces.​

Answer 1

Answer:

22

Step-by-step explanation:

As per question:

Euler's Formula is for any polyhedrons. i.e.

F +V -E = 2

Given,, F = a and V = 40 and E = 60

According to the formula:

a + 40 - 60= 2

a - 20 = 2

a - 20 = 2a = 20 + 2

a - 20 = 2a = 20 + 2a = 22
