Yes.
It's not true. As with all solid figures, polyhedra have volume and surface area.
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.
In general: figures, polygons, polyhedrons, shape, irregular, regular... Other examples: circle, triangle, square, quadrilateral, rectangle, rhombus, parallelogram, trapezoid, hexagon, heptagon, octogon... 13-gon -- seriously, 15-gon, centagon... it goes on...

A sphere.
A prism is a polyhedron.
A sphere has no faces an corners. The term "faces" and "corners" are applied to polyhedrons, figures with flat surfaces.
Well, darling, those solid figures with more than six faces are called polyhedrons. They're like the cool kids of geometry, strutting around with their multiple faces and edges. So next time you see one, just remember they're not just any old shape - they're polyhedrons, honey.

False. Cylinders and cones are not just polyhedrons with circular bases.
polyhedrons need flat face and edges, corners which cylinder cones don't have.
