Question

Use Euler’s Formula to find the missing number. Faces: 8 Edges: _____ Vertices: 6

Answer 1

Answer:

The number of edges is $E=12$

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

$V- E + F = 2$

In this problem we have

$F=8, V=6$

substitute and solve for E

$6- E + 8 = 2$

$E=6 + 8 -2=12$
