a polyhedron is any 3d figure with all flat polygons for sides(polygons have straight sides)
A prism is a polyhedron.
No. Polyhedrons are any shape with multiple sides. A triangle and a prism are just two different kinds of polyhedrons.
Yes, an empty box is and No, polyhedrons don't have to be.
Polyhedrons are three-dimensional geometric shapes with flat polygonal faces, straight edges, and vertices. They are characterized by their number of faces, vertices, and edges, which are related by Euler's formula: ( V - E + F = 2 ), where ( V ) is vertices, ( E ) is edges, and ( F ) is faces. Polyhedrons can be classified into regular (Platonic solids, where all faces are identical) and irregular types. Their faces can vary in shape, but they are always formed by connecting edges at vertices.
False. Cylinders and cones are not just polyhedrons with circular bases.
polyhedrons need flat face and edges, corners which cylinder cones don't have.
