A polygon is a plane (2-dimensional) object bounded by straight lines. A polyhedron (not polyhendron!) is a solid (3-dimensional) object bounded by polygonal faces.
So, pyramids and some prisms are polyhedra. A cylinder is a type of prism but, because two of its faces are circular, those faces are not polygons. As a result a cylinder is not a polyhedron.

How are prisms and cylinders different?
Prisms have polygons as bases whereas cylinders have circles as bases. In a way, a cylinder is like a circular prism.
What are the the similarities about prisms and pyramids?
They are convex polyhedra. composed of at most two types of polygons..
What are examples of prisms pyramids cylinders and cones in real life?
Prisms: Feed troughs, bathtubs, and boxes. Pyramids: Pyramids of Egypt and the Aztecs. Cylinders: Cans, pistons, tubes, and pipes. Cones: Ice cream cones, funnels, and the bottom part of a water tower.
Are pyramid and prism the only polygons?
All shapes are polygons * * * * * Wrong! Neither is a polygons. Polygons are two-dimensional shapes enclosed by straight lines. Even a common shape, such as a circle is NOT a polygon. Pyramids and prisms are two of an infinite variety of polyhedra.
The difference between cylinders and prisms is that cylinders have 2 bases whereas the bases of prisms are?
... whereas one of the "bases" of prisms are vertices.
