what is the defference between polyhedron and prisms
Polyhedron is a solid made up of polygonal regions (called its faces). These faces meet at edges (which are line segments) and the edges meet at the vertices (which are points).:
In the following figures, first two figures are polyhedrons where as the remaining two figures are not polyhedrons.
A prism is a polyhedron whose base and top are congruent polygons and whose lateral faces are parallelograms in shape.
The following figure is a prism.
All prisms are polyhedrons bit the converse is not true.
Hope! This will help you.
