Question

If a figure has five vertices and eight edges, how many faces does it have?

Answer 1

Euler's formula works well here.

Answer 2

Cube -
Edges = 12
Faces = 6
Vertices = 8

Vertices + Faces - Edges = 2

This works everywhere.

Answer 3

\( \color{Black}{\Rightarrow 5 + Faces - 8 = 2}\)

\( \color{Black}{\Rightarrow -3 + Faces = 2}\)

Answer 4

Add three to both sides.
