That's a "lens".
cylinder is the name for a circular prism
It could be called a square prism but a more common name would be a cuboid.
Both are prisms. A prism is a 3D shape which has a uniform cross section, so anywhere along it's length where you take a slice you always see the same shape. To say which prism you mean we add the name of this cross section 'triangular prism', 'hexagonal prism' etc. We have a special name for a circular prism - a cylinder. Also, a rectangular prism is a cuboid.
It is the height of the prism. There is no need for another name!

A prism cannot be used to name an ordered pair.
Twice the name. A prism with an n-sided base will have 2n vertices.
A twelve-sided prism is called a dodecagonal prism. The prefix "dodeca-" denotes twelve sides, while "gon" refers to a polygon. In geometry, a prism is a polyhedron with two parallel and congruent faces called bases, and its other faces are parallelograms. A dodecagonal prism would have twelve sides, twelve vertices, and twenty-four edges.
