Prisms are a subset of polyhedra (or polyhedrons!)
Polyhedra (singular = polyhedron).
WHat is the difference between polyheron and platonic solid
Yes. It is one of the five regular polyhedra known from ancient Greek times or earlier.See http://www.math.rutgers.edu/~erowland/polyhedra.html .
The flat surfaces of all polyhedra are called faces and a rectangular prism is simply one kind of polyhedron.

No. A pyramid is a polyhedron. Many pyramids are polyhedra.
Not exactly. A tetrahedron is a polyhedron. Many tetrahedra are polyhedra.
A triangular prism is a polyhedron. Polyhedra is a plural term.
The plural of polyhedron is polyhedra (same principle as "phenomenon" and "phenomena".
Each polyhedron is a kind of solid object. Some solid objects -- for example, a sphere or a torus -- are not polyhedra, but every solid object can be closely approximated with a polyhedra.
A hexagonal prism is a polyhedron. Many hexagonal prisms are polyhedra.
There are different formulae for different polyhedra and these depend on what information about the polyhedron is given.

Poly = manyHedron = corner (in 3-d space) So a polyhedron is a 3-d shape having many vertices (solid angles). The plural of polyhedron is polyhedra.
There are infinitely many polyhedra. There is no limit to the number of faces that a polyhedron can have. Given any polyhedron, simply cut off one vertex so that you will have a polyhedron with one more face. Also there are several versions of polyhedra with the same number of faces. A hexahedron, for example, can be a parallelepiped or a pentagon based pyramid or a triangular based dipyramid.
