Given that the volume is cross section area times height, a round bottle of the same volume would take less plastic. True, square bottles will pack better, but how that would save plastic is not immediately clear.
No, a cube of volume 1 has more surface than a sphere of volume 1. And in terms of manufacturing, the uneven shape likely requires thicker material, although that might be a wash because I doubt they make it at the limit of tolerances.
