Question

Using Euler's Formula, find the unknown value
1) When F=20, V= 12, find E​

Answer 1

Answer:

30

Step-by-step explanation:

Euler's formula = Faces(F) + vertices(V) = Edges(E) + 2

= 20 + 12 = E +2

= 20+12-2 = E

= E = 30

so E = 30

Answer 2

Answer:

according to euclers formula E+2=F+V

so E+2 =20+12

E+2 =32

E =32-2=30

E =30
