The pentagonal prism has seven sides including the bases
There is no equation - the answer is explicit in the name.A pentagonal prism has pentagonal bases. A pentagon has 5 sides. It could not be simpler!
The base of a pentagonal prism is a pentagon. Just like a square pyramid has a square for a base, a pentagonal prism has a pentagon for a base.

The number of diagonals per vertices can be found by taking n(number of sides) minus 3, or n-3. Thus a pentagonal prism will have 5 sides per base, making the formula 5-3=2. There are 2 diagonals per vertex in a pentagonal prism. Source: My math teacher
