Parallelepiped.
A hexagon is a six-sided polygon. A four-sided polygon is a quadrilateral, quadrangle, or tetragon.
Cube, Cuboid. Any prism with a quadrilateral cross section
Two six-sided bases connected by rectangles.
A hexagon, a triangular prism, a pentagonal pyramid, two-quadrilateral pyramids attached by their quadrilateral faces are some options. Take your pick!
A rectangle is a case of quadrilateral, which is a 4 sided polygon. So the answer would be no rectangle has 6 sides. A rectangular prism (like a box or a cube) has six faces, though. Some people may refer to faces as sides.
A six-sided prism is called a RHOMBOHEDRON. * * * * * A more general form, which does not require edges to be the same length (as in the above case), is a parallelepiped.

A hexagonal prism has bases that are hexagonal. It has eight faces in all (octahedron).A rectangular prism has bases that are rectangles . It has six faces in all (hexahedron).
It is an oxymoron: a 2-dimensional six-sided shape which has four sides!
A 6 sided planar (2-d) polygon is called a hexagon.A 6 sided 3-d shape is a hexahedron, which might also be a cube, rectangular prism, die, pentagonal pyramid, or quadrilateral di-pyramid depending on the exact shape.
Amethyst is a form of quartz. Quartz belongs to the trigonal crystal system. The ideal crystal shape is a six-sided prism terminating with six-sided pyramids at each end.
The prefix hex- denotes a six sided polygon, so a hexagonal prism will have a six-sided base and, in total, will have eight faces: it is an octohedron.Provided the faces are all regular the hexagonal prism is referred to as a semiregular polyhedron, but could be defined in other terms if the faces are irregular.

The mineral with a six-sided prism crystal structure is typically quartz, which belongs to the hexagonal crystal system. Quartz is composed of silicon dioxide (SiO2) and is known for its hardness and variety of colors. Its six-sided prisms can be observed in natural crystal forms, making it one of the most common and recognizable minerals on Earth.
