A polyhedron is a solid object bounded by polygons. Polygons are plane shapes [bounded by straight lines]. The curved surface of a cone is not a polygon and so the cone is not bounded by polygons and therefore, a cone is not a polyhedron.

Yes, a polyhedron is a solid bounded by polygonal regions, which are the faces of the polyhedron. These faces are formed by the intersection of planes, and the edges of the polyhedron are the line segments where these faces meet. The vertices are the points where the edges converge. Thus, a polyhedron is defined by its flat faces, straight edges, and vertices.
Yes. It is a solid figure that is bounded by polygonal faces.

A polyhedron is a three-dimensional object, not two-dimensional.
No, a polyhedron is a three-dimensional solid bounded by polygonal faces. Each face is a flat polygon, and the edges of these polygons meet at vertices. The term "two-dimensional solid" is a mischaracterization, as polyhedra occupy three-dimensional space.
A polyhedron is a simply connected 3-dimensional simply connected shape which is bounded by polygonal faces. A dodecahedron is a special case of a polyhedron: it is a polyhedron with 12 faces.
A polygon is a flat, two-dimensional shape with straight sides, defined by its vertices and edges. In contrast, a polyhedron is a solid bounded by polygonal regions, formed by the intersection of planes in three-dimensional space. These polygonal faces can vary in number and shape, creating various types of polyhedra, such as cubes and tetrahedra. Thus, while a polygon refers to a 2D figure, a polyhedron refers to a 3D solid.
