When given a cylinder with radius, height and thickness, how does one go about computing the amount of material used in making the cylinder?
Initially I thought the amount would be:
[itex]Material=2\pi r^{2}t+2\pi r h t[/itex]
where [itex]t[/itex] is the thickness of the cylinder.
Looking at this equation however, I realized that by default (without given a thickness for the cylinder) one would assume a thickness of one. This didn't make sense to me, however, because a surface with unspecified thickness should have no thickness right?
Perhaps I am thinking about this in the wrong way.
