a polyhedron * * * * * That is only if it is bounded by plane faces. A sphere, for example, is a three dimensional shape but is not a polyhedron: it is a solid shape.
then it's a - Dodecahedron
A Pyramid
A dodecahedron is a polyhedron with 12 faces.A dodecahedron is a three-dimensional shape having twelve plane faces.
triacontahedron
A two-dimensional shape with three sides is a triangle. A three-dimensional shape with three faces is a cylinder.

A shape that has 10 sides (two dimensional) is called a decagon. A shape that has 10 faces (three dimensional) is call a decahedron.

A dodecahedron is a polyhedron with 12 faces.A dodecahedron is a three-dimensional shape having twelve plane faces.
An octahedron is a polyhedron with eight faces, twelve edges, and six vertices
A cuboid.
There is none you idiot
It is a triangular prism
Octagon. * * * * * An octagon is 2-dimensional. The regular 3-d shape (all faces the same) is the octahedron, but a hexagonal prism also has 8 faces.
A double helix
