Three dimensional figures made of polygons are called polyhedrons?
Yes.
Why polyhedrons have only area but not volume?
It's not true. As with all solid figures, polyhedra have volume and surface area.
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.
What are the Geometric names for figures?
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...

What is the name for round threedimensional object?
A sphere.
Are prisims polyhedrons or not polyhedrons?
A prism is a polyhedron.
A sphere has how many faces and how many corners?
A sphere has no faces an corners. The term "faces" and "corners" are applied to polyhedrons, figures with flat surfaces.

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
