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
$F + V - E = 2$
So, for a cube,
number of faces $= 6$
number of vertices $= 8$
number of edges $= 12$
Therefore, $6 + 8 - 12 = 14 - 12 = 2$
Hence, verified.
