Answering your questions one at a time.
1 - What is a platonic solid?
A platonic solid is one with all faces congruent polygons, meaning that they all have the same number of sides, vertices and angle size.
2 - How many are there?
There are only and exactly five.
3 - What are their names?
Tetrahedron
Cube (but when talking about Platonic solids, it is commonly referred to as a "hexahedron").
Octahedron
Dodecahedron
Icosahedron
Note: These individual platonic solids can be identified by their unique Schlafli Symbol. This is demonstrated through the following:
{p,q}
p = Number of vertices at each face
q = Number of faces at each vertex
So for a dodecahedron, the Shlafli Symbol would be {5,3}, because a pentagon has five {5, or p} vertices, and at any individual vertex three {3, or q} faces meet.
Understand? Great!
Plato discover them
No. All the faces of a Platonic solid are identical regular polygons.
A cube is the only platonic solid which is a prism.
The Name Platonic solid Comes from Plato the second main reseacher of the five solids. Pythagoras was the one discovered the platonic solids

No. All the faces of a Platonic solid are identical regular polygons.
WHat is the difference between polyheron and platonic solid
A trapezoid is not a platonic solid. There are only five platonic solids. They are the tetrahedron, hexahedron, octahedron, dodecahedron, and icosahedron.
No, a cone is not a Platonic solid. The Platonic solids are the five regular polyhedra: tetrahedron, cube, octahedron, dodecahedron, and icosahedron.
A cube is the only platonic solid which is a prism.
