According to Euler’s formula for any solid, the number of Faces (F) and vertices (V) added together is exactly two more than the number of edges (E).

Solution:
According to Euler's formula:
$F+V=2+E$
or $F+V-E=2$
Therefore, for a cube,
number of faces $=6$
number of vertices $=8$
number of edges $=12$
Thus, $6+8-12=14-12=2$
As a result, verified.
