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.

yes, they are different.
A triangular prism has 9 edges!
