There are 8 edges on a rectangular prism

There is a trick to figure out these thing and

Here it is, you have to know the amount of

Faces and times that number by 2 to get the

Number of edges. You take the number of faces

Then add 2 to get the number of vertices.

That is so wrong. Obviously a rubbish trick.

The Euler characteristic requires the number of

F + V = E + 2 where

F = number of faces (6)

V = number of vertices (8)

and

E = number of edges (12)

A rectangular prism is essentially a cuboid or a brick shape. Easy to check out.
