A polyhedron is a math formula and information about it can be found in a math textbook or on Math Is Fun, Euler's Polyhedron Formula, Math Munch and Open Study.
first, find the volume of each shape that is in the polyhedron. then you add all of them together.
No. A polyhedron has plane faces; a cylinder has one curved face.
square and hexagon
One polyhedron; many polyhedra. Simple,wasn't that?
The number of edges and vertices ina polyhedron will depend on the polyhedron one selects either to study, build or etc...
A polyhedron has only polygonal faces and any one of them can be considered a base. Therefore a polyhedron with 0 bases cannot exist.
A polyhedron is a closed figure with several (planar) sides, and all its sides are planar. A non polyhedron does not have these properties, maybe it is not closed, maybe one or more of the sides is a curved surface. In some branches of topology the sides of a polyhedron cannot intersect each other.
It is a pentagon.
It is a pentagon.
pyramid
A cone.
No, they are the faces of the polyhedron.
