What is the name for a three dimensional shape?
These could be called solids.There are lots of three dimensional shapes. Cubes, spheres, cylinders, cones, toroids, pyramids, helixes, the various polyhedrons..
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
Which of the following are not polyhedrons?
Cone, cylinder.
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.
Why aren't cylinders cones and spheres polyhedrons geometry?
polyhedrons need flat face and edges, corners which cylinder cones don't have.
Cones and polyhedrons both have only one base?
false
Why are cylinders and cones not considered to be polyhedrons?
A polyhedron is defined as a "geometric solid in three dimensions with flat edges and straight faces". As both cylinders and cones have curved faces, neither are polyhedra.
