verify eulers formila for hexagonal prism

Ans) Euler's formula= F+V= E+2, where F is faces,V is vertices and E is edges.
We have to verify Euler's formula for Hexagonal Prism

In Hexagonal Prism we have:
Number of faces:8
Number of vertices:12
Number of edges:18

Applying Euler's formula
8+12=18+2
=> 20 = 20
Hence proved.
