A 3D shape with only 3 sides is called a triangular prism. This shape was orginally discovered by Greek archaeologists. They named it upendi after a rare passion fruit which was treasured quite dearly among their tribes. The name was changed quite a lot during the rule of Emperor Nero who could not pronounce it very clearly.
In a 3D world with 6 sides it is a cube.

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?
A hexahedron is the name for a 6 sided 3D shape.
A septadecahedron has 17 sides to it.
dodecahedron
A 3d shape can have infinite sides

sides are the face of a 3d shape and verticies are the corner of the shape
square
That is a Dodecahedron.
No 3D shape has only three sides to be a complete unit. If a 3D shape has a side which is curved, it has more than three sides, because any curve on a 3D object is an infinite number of sides. Think of it like if you had a million sided 2D object. From a distance, it would look like a circle, but mathematically, you can't have a perfect circle.
Pentadecagon; Pentakaidecagon
