It need not be. A sphere, for example, has no rectangles nor polygons and no parallel planes either.
It is unlikely that the question is about a polyhedron which is a 3-dimensional solid bounded by polygons. The minimum number of edges for a polyhedron is 6: the question appears to suggest just 4.
A prism isa polyhedron- that is, 3-dimensional shape bounded by polygons. It has two parallel bases that are identical polygons. The corresponding sides of these polygons are joined together by quadrilaterals.A pyramid is also a polyhedron. It has a polygonal base of n sides and n triangles, attached to each of the sides of the polygon, that meet at an apex above [or below] the plane of the polygon.AA prism isa polyhedron- that is, 3-dimensional shape bounded by polygons.

Polyhedra are 3-dimensional shapes bounded by polygons. Polygons are flat [plane] shapes bounded by straight lines. So a polyhedron cannot have any curved faces.
They are all polygons: two-dimensional shapes, bounded by straight lines.
I think you mean polyhedron...if that's what you mean then...its a three dimensional object bounded by polygons, with each edge shared by exactly two polygons
A hexagon is a plane (2-dimensional) figure whereas a hexahedron is a solid (3-dimensional) shape. A hexagon is bounded by six straight lines whereas a hexahedron is bounded by six polygons.
A polyhedron is a three dimensional shape. A polyhedron is bounded by a number (four or more) of polygons and encloses one space.
Polygons are closed two dimensional shapes which are bounded by three or more straight lines. There are infinitely many of them so it is not possible to name them all.
squares, rectangles, trapezoids, rhombuses
A parallelogram is a closed 2-dimensional shape bounded by two pairs of parallel sides.
A polygon is a plane (2-dimensional) object bounded by straight lines. A polyhedron (not polyhendron!) is a solid (3-dimensional) object bounded by polygonal faces. So, pyramids and some prisms are polyhedra. A cylinder is a type of prism but, because two of its faces are circular, those faces are not polygons. As a result a cylinder is not a polyhedron.
No. A polygon is a plane area bounded by straight lines. The key term in this context is "plane". It is, therefore, 2 -dimensional shape. A solid, which is bounded by faces that are polygons, is called a polyhedron (plural = polyhedra).
