The answer is 13- for more detail:
How many planes of symmetry does a decagon prism have?
6
5
5
there are two plane symmetry on triangular prism.
3D shapes don't have lines of symmetry they have plane's of symmetry.
A hexagonal prism is a prism composed of two hexagonal bases and six rectangular sides.
7
A hexagonal prism has 6 rectangular faces.
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.
