The description given fits that of cones
The cube have: -- six (6) faces -- twelve (12) edges -- zero (0) curved surfaces -- eight (8) vertices
A shape that is not a polyhedron is a sphere. Unlike polyhedra, which are three-dimensional shapes with flat polygonal faces, a sphere has a curved surface with no edges or vertices. Other examples include cylinders and cones, which also possess curved surfaces and do not meet the criteria for polyhedra.

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.

A tetrahedron is a triangular based pyramid that has 4 faces, 6 edges and 4 vertices.
2d shapes do not have edges or vertices
Vertices = 4Faces = 4 Edges = 6.
This all depends on the shape. Different shapes have different face, edges, vertices.
square based triangle
no numbers have the same number of edges and vertices
There are two plane faces and a curved face, two edges and no vertices.
