Question

Using Euler's formula 5 faces, 9 edges & find vertices?
a) 4
b) 6
C) -4​

Answer 1

euler's formula = F+V = E+2

5+V = 9+2

V=11-5 =6

Answer 2

Answer:

b) 6

Step-by-step explanation:

According to Euler's formula

V-E+F=2

F=5

E=9

V=?

By putting values we get

V-9+5=2

V-4=2

V=2+4

V=6

So 6 is the correct answer.

Hope it helps.
