its a lens...1 curved edge = a circle, 1 flat surface = back, 1 curved surface = front.
(these are used in some battery-less flashlights, as an example.)
A Cylinder
A football has a curved surface and polygons are flat. You can approximate a curved surface quite well if you use enough polygons but each polygon will still be flat and a football does have a curved (and rough) surface. Using a few thousand polygons you can create an approximation of a football with stitching seams and every detail but you will not have a curved surface you will have an approximation of a curved surface.
A cuboid has 6 flat faces but no curved surfaces. ..________ ./............../| /_______/.| |..............|.| |..............|./ |_______|/
A plane horizontal surface with no depth refers to a flat area on a curved surface.
When information is moved from a curved surface( like the Earth) to a flat surface ( like a map), distortion occurs.

A Cylinder
It has a flat base, a curved surface area, a circular edge and one vertex.
Such a shape probably does not have a specific name.
