Question

Using Euler's formulas find the number of faces if edges and vertices are 60 and 40 respectively​

Answer 1

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 + 2

a = 22
