Question

Using Euler’s formula , find the unknown. Faces = 9 Vertices = ( ? ) Edges = 16​

Answer 1

Answer:

Euler’s formula: F + V - E = 2

Where , F = Faces, V = Vertices and E = Edges

i) F + 6 - 12 = 2

F = 2 + 6

F = 8

ii) 5 + V - 9 = 2

V-4 = 2

V = 6

iii) 20 + 12 - E = 2

32 - E = 2

E = 30
