A sphere.
How about a sphere
That's a Sphere not Cylinder cuz it had flat Circles Above and
There are any number of shapes without flat faces including: > circle > ellipse > blob
flat surfaces on any polyhedron are called faces
No. A triangle is a two-dimensional polygon (flat figure). It has sides that consist of three line segments, with an interior area. Only a three-dimensional form (polyhedron) can have faces. Triangles serve as faces for any number of polyhedrons, such as pyramids.
It is a definitional requirement. If any face is not flat, then it is not a polyhedron.

Polyhedron.
Any figure with 8 faces is an octahedron. If it has 18 edges, it is a hexagonal prism.Any figure with 8 faces is an octahedron.
