They are both simply connected 3-dimensional shapes, all of whose faces are polygons.
The five platonic solids are the tetrahedron, hexahedron (cube), octahedron, dodecahedron, and icosahedron.
Icosahedron can be bigger
Twenty.
If you mean the regular polyhedra, they are: tetrahedron, cube (or hexahedron), octahedron, dodecahedron, icosahedron, (Plato's 50) plus: small stellated dodecahedron, great stellated dodecahedron, great dodecahedron, great icosahedron for 9. Maybe a sphere is a perfect curved 3D figure.
Tetrahedron, Cube Octahedron Dodecahedron Icosahedron
Some examples of solids are cube, sphere, cylinder, cone, pyramid, prism, tetrahedron, dodecahedron, octahedron, icosahedron, torus, cuboid, rhombic dodecahedron, ellipsoid, oloid, trapezohedron, truncated cone, truncated cuboctahedron, truncated dodecahedron, truncated icosahedron.
