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.
Is an empty box a polyhedron. Do polyhedrons have to be solid?
Yes, an empty box is and No, polyhedrons don't have to be.
Do polyhedrons have right angles?
not all
Are cones polyhedrons?
no because it has curved faces.
What are 3-D shapes called?

Is an empty box a polyhedron. Do polyhedrons have to be solid?
Yes, an empty box is and No, polyhedrons don't have to be.
Cylinders and cones are just polyhedrons with circular bases?
False. Cylinders and cones are not just polyhedrons with circular bases.
Why aren't cylinder cones and spheres polyhedrons?
polyhedrons need flat face and edges, corners which cylinder cones don't have.
Are polyhedrons symmetrical?
not all, but some
What shapes are the lunar craters?
Polyhedrons
Do polyhedrons have right angles?
not all
Why aren't cylinders cones and spheres polyhedrons geometry?
polyhedrons need flat face and edges, corners which cylinder cones don't have.
Why are cylinders and cones not considered to be polyhedrons?
Cylinders and cones are not considered polyhedrons because they do not have flat faces, which is a defining characteristic of polyhedrons. Polyhedrons are three-dimensional shapes made up of flat surfaces, while cylinders and cones have curved surfaces. Additionally, polyhedrons have straight edges where faces meet, whereas cylinders and cones have curved edges. Therefore, cylinders and cones are classified as curved surfaces rather than polyhedrons.
