Question

Faces are 8, Edges are 7. Find the vertices by Euler's Formula​

Answer 1

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

Answer 2

Step-by-step explanation:

By euler’s Formula, We Have

F + V - E =2

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
