You cannot make a hexagon out of rectangles and so you will never be able to make the two bases of the hexagonal prism. And these two hexagons, after all, are what give the shape its name.
It depends on what kind of prism you mean. For example, a rectangular prism has 6 bases and a triangular prism has 5 bases. A triangular prism only has two bases.
A triangular prism has 2 bases on it!
a pentagonal prism has 2 bases
It depends. It has to have at least 24. If the hexagon is a regular hexagon, then only 24.
