Since a hexagon is a horizontal plane figure it cannot have a horizontal plane of symmetry.
Lines of symmetry are 2 dimensional. Planes of symmetry are 3D.
there is 9 planes of symmetry in a cube
it has 5 planes of symmetry
There are infinite planes of symmetry in a cylinder in the same way that a circle has infinite lines of symmetry.
6 planes of symentry

Four.
There is, as far as I can tell, only one "line" of symmetry: the sixfold rotational axis passing through the vertex and the center of the base. In addition, there are six planes of symmetry; three that pass through opposite vertices of the hexagon and three that pass through the midpoints of the sides of the hexagon. For any pyramid in which the base is a regular polygon with n sides and the apex is above the centre of the polygon, there are nplanes of symmetry (for an even-sided polygon, half the planes pass through opposite vertices and half of them pass through the midpoints of opposite sides; for an odd-sided polygon, each plane passes through one vertex and the midpoint of the opposite side). A hexagon has six sides, so it has six planes of symmetry.
Lines of symmetry are 2 dimensional. Planes of symmetry are 3D.
There are 3 planes of symmetry in a rectange.
there is 9 planes of symmetry in a cube
A cube has three planes of symmetry.
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.
it has 5 planes of symmetry
There are infinite planes of symmetry in a cylinder in the same way that a circle has infinite lines of symmetry.
A rectangular solid that is not a cube has 3 planes of symmetry.
