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.

There are no lines of symmetry in a 3d figure.The right question is how planes of symmetry are there in a pentagonal pyramid.Then the correct answer is 5 planes of symmetry.

A pentagonal prism has 5 vertical axes of symmetry that pass through the center of each of the pentagonal bases and the midpoint of the opposite base edges. Additionally, it has 1 horizontal axis of symmetry that runs through the midpoints of the two pentagonal bases. Therefore, a pentagonal prism has a total of 6 axes of symmetry.

3D shapes don't have lines of symmetry they have plane's of symmetry.
