Polyhedrons are defined as three-dimensional shapes with flat polygonal faces, straight edges, and vertices. Therefore, objects that do not meet these criteria, such as spheres, cylinders, and cones, are not considered polyhedrons. Additionally, shapes with curved surfaces or those that are not fully enclosed do not qualify as polyhedrons.
What else can I help you with?
All polyhedrons are prisms or pyramids.?
No. Polyhedrons are any shape with multiple sides. A triangle and a prism are just two different kinds of polyhedrons.
