Faces (F)	$6$
Edges (E)	$12$
Vertices (V)	$8$

Using Euler’s formula, complete the following table:

For any polyhedron, $\mathrm{F}+\mathrm{V}-\mathrm{E}$$=$_____, where $\mathrm{F}$ stands for number of faces, $\mathrm{V}$ stands for number of vertices and $\mathrm{E}$ stands for number of edges, and this relationship is called Euler's formula.
