A 6 sided hexagon has 6 vertices and so 3 hexagons will have 3*6 = 18 vertices
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.
A sphere has no corners, it is a 3-D circle.
Add one to a hexagons number of vertices
7 of them.

Infinitely many - if you have an infinite supply of the materials from which they are made.
Steel companies make steel bars in hexagons
None. It is not possible to make a sphere in that fashion.
idk, how about you stop being lazy & count a socccer ball. (: kthanks. a soccer ball is a sphere and not a circle. nice try on being a smartass. without the diameter given the amount of hexagons in a circle is infinite. as I'm sure the one who posed this question knows. the library of babel is a literary piece describing the infinite nature of this very paradigm.
there is 7 hexagons in the design
None. Though there can be ten if the hexagons are concave hexagons.
6
They have 6
None.
