Answer:
The number of edges is [tex]E=12[/tex]
Step-by-step explanation:
we know that
The Euler's formula state that, the number of vertices, minus the number of edges, plus the number of faces, is equal to two
so
[tex]V- E + F = 2[/tex]
In this problem we have
[tex]F=8, V=6[/tex]
substitute and solve for E
[tex]6- E + 8 = 2[/tex]
[tex]E=6 + 8 -2=12[/tex]
