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!
Five.Five.Five.Five.
A prism with an n-sided base will have 2n vertices, n + 2 faces, and 3n edges. A pentagonal prism has 15 edges.
A hexagonal prism's base is called a hexagonal base. The names of prisms are given according to the shape of their bases. A hexagonal prism has a base that is shaped like a hexagon. Similarly, a pentagonal prism has a pentagonal base.

A pentagonal prism would fit the given description
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.

A prism with an n-sided base will have 2n vertices, n + 2 faces, and 3n edges. A pentagonal prism has 15 edges.
The pentagonal prism has seven sides including the bases
A hexagonal prism's base is called a hexagonal base. The names of prisms are given according to the shape of their bases. A hexagonal prism has a base that is shaped like a hexagon. Similarly, a pentagonal prism has a pentagonal 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
