Three dimensional figures made of polygons are called polyhedrons?
Yes.
Why are three dimensional figures with a curved surface not polyhedrons?
Three-dimensional figures with a curved surface are not considered polyhedrons because polyhedrons are defined as solids with flat polygonal faces, straight edges, and vertices. Curved surfaces lack these flat faces and straight edges, which are essential characteristics of polyhedrons. Examples of shapes with curved surfaces include spheres and cylinders, which do not fit the definition of a polyhedron. Thus, the presence of curved surfaces distinguishes these figures from polyhedra.
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 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.

What is the name of solid figures with more than six faces?
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.
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.
Cylinders and cones are just polyhedrons with circular bases?
False. Cylinders and cones are not just polyhedrons with circular bases.
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...
Why aren't cylinder cones and spheres polyhedrons?
polyhedrons need flat face and edges, corners which cylinder cones don't have.
