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.

The shape you are describing is a cylinder. A cylinder has two flat circular faces (the top and bottom) and one curved surface that wraps around the sides. It has no edges or vertices where flat surfaces meet, as the curved surface is continuous.
A tetrahedron is a triangular based pyramid that has 4 faces, 6 edges and 4 vertices.
Yes, a sphere has a curved surface. Unlike flat shapes, the entire surface of a sphere is smooth and continuously curves outward from its center. This curvature is uniform in all directions, making the sphere a three-dimensional shape with no edges or vertices.
2d shapes do not have edges or vertices
3D shapes that only have flat faces are known as polyhedra. Examples include cubes, tetrahedrons, and octahedrons. Each of these shapes is composed entirely of flat polygonal faces, edges, and vertices. In contrast, shapes like spheres or cylinders have curved surfaces and do not fit this category.
Vertices = 4Faces = 4 Edges = 6.
This all depends on the shape. Different shapes have different face, edges, vertices.
