Each face of a polyhedron must be a polygon: a flat surface bounded by straight lines. So, if any of the faces is curved, the shape is not a polyhedron.

Are not polyhedrons check all that apply.?

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 shapes are polyhedrons?

Polyhedrons are three-dimensional shapes with flat faces, straight edges, and sharp corners, known as vertices. Examples of polyhedrons include cubes, pyramids, prisms, and dodecahedrons. These shapes have a closed surface and are made up of polygons, which are two-dimensional shapes with straight sides.
