Three.
This depends on the type of prism. If the shapes on the ends are pentagons, the prism has 6 planes of symmetry. If they are hexagons, it has 13 planes of symmetry. It has the same number of planes of symmetry as the shapes on the end have lines of symmetry, plus 1.

Ah, a pentagonal prism is a beautiful shape, friend! It has five planes of symmetry, just like the number of sides it has. Each plane can be thought of as a mirror that can reflect the prism perfectly. Isn't that just lovely?
There are 3 planes of symmetry in a rectange.
Three.
A rectangular solid that is not a cube has 3 planes of symmetry.

there are two plane symmetry on triangular prism.

Three.
3D shapes don't have lines of symmetry they have plane's of symmetry.
Two.
The answer is 13- for more detail:

It must have at least one.
