A 3d shape can have infinite sides
sides are the face of a 3d shape and verticies are the corner of the shape
2D shape = Decagon 3D shape = Decahedron
Tetrahedron
Dodacohedron, I think.

A 3d shape can have infinite sides
In a 3D world with 6 sides it is a cube.

That is a Dodecahedron.
Pentadecagon; Pentakaidecagon
2D shape = Decagon 3D shape = Decahedron
A quadrilateral is a plane or 2d figure with four sides. A 3d shape (object) has a name ending with -hedron, eg a tetrahedron which is a four sided 3d shape. A 3d quadrilateral has no meaning. Sides (edges) do exist in 3d shapes, but a more pertinent attribute is faces. Do you mean by "3d quadrilateral" a 3d shape which has a quadrilateral as a base and at most 4 or 5 other sides, ie a pentahedron (usually called a square pyramid) or a hexahedron (some types of which are called cuboids and cubes)? Please re-ask using consistent terminology, eg What is a 3d shape with one pair of parallel faces and 6 faces?
triangular pyramid.
Tetrahedron
