Why cans of soup are shaped the way they are
> If we wanted to use a shape that packed perfectly efficiently, we’d use some kind of cuboid... But we don’t see many cubes on shelves. Let's look at cylinders now...The only real reason the article gives against using cuboids is that "the edges would be stress points", but it goes on to imply that this is mostly solved with "filleted (rounded) edges to reduce stress concentrations and to make them easier to manufacture."I enjoyed the rest of the article relating to the optimal dimensions of the cylinder, but I still don't really understand why more products don't use cuboids (with or without filleted edges). Surely the space savings for shipping and shelving would be pretty significant, no?
