A Sphere, a cylinder and a cone.
Some examples are a sphere, a cylinder and a cone.
The three main types of geometric solids are polyhedra, which are three-dimensional shapes with flat polygonal faces; curved solids, which include shapes like spheres and cylinders with curved surfaces; and composite solids, which are formed by combining multiple geometric solids. Each type has distinct properties and characteristics that define their structure and dimensions.

The surface area of a polyhedron can be calculated by first calculating the area of each of its polygonal surfaces and adding these together.The surface area of some curved solids (sphere, cylinder, cone) can be calculated from formula but for most curved solids are more complicated and require integration.
a sphere has 0 flat serfaces 0 vertices
Solids that have no perpendicular faces include curved surfaces, such as spheres and cylinders. In these shapes, all points on the surface are equidistant from the center (in the case of a sphere) or maintain a constant radius from a central axis (in the case of a cylinder). Other examples include cones and ovoids, where the surfaces are continuously curved without any straight edges that meet at right angles.
Three types of solids that do not have any faces or edges are spheres, cylinders, and cones. A sphere is perfectly round and has no edges or vertices, while a cylinder has curved surfaces but flat circular bases. A cone features a circular base and a curved surface that tapers to a point, but it also lacks distinct edges and faces.
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.
