1) F = ?
V= 6
E = 12
By using Euler's formula
F + V = E + 2
F + 6 = 12 + 2
F + 6 = 14
F = 14 - 6
F = 8
2) F = 3
V = ?
E = 9
By using Euler's formula
F + V = E + 2
3 + V = 9+2
3 + V = 11
V = 11 - 3
V = 8
3) F = 20
V = 12
E = ?
By using Euler's formula
F + V = E + 2
20 + 12 = E + 2
32 = E + 2
32-2 = E
E = 30
