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.

How are pyramids and cones different than prisms and cylinders?
They depend on radius rather than perimeter.
What kinds of 3d shapes are there?
There is prisms and pyramids. There are also spheres and cylinders
How are pyramids and prisms named?
They are both named according to the polygons that form their base(s).

How are cones and cylinders similar to pyramids and prisms?
cones are similar to pyramids because they come to a point, also known as the vertex. Cones and pyramids are also conic. Cylinders are similar to prisms because their base, no matter what shape, will translate (slide) all the way up the middle to the top. Basically, their 2 bases should always always always be congruent. Prisms and cylinders are also cylindric.

Are polyhedrons sometimes not prisms or pyramids?
they are not sometimes prisms
What are the faces of prisms usually made of?
polygons
