Regular cans are somewhat inefficient shapes as well, shorter and fatter would be more economical, but less ergonomical and for once that won out, for a while anyway. Now we get designed by marketing instead.

Yeah, there's an awesome video on aluminum drink cans from TheEngineerGuy on YouTube. The ideal shape for holding pressure with minimal material is a sphere, but there's 2 problems with that: They roll, and can't be packed as efficiently as cylinders.
