        You sure about that?

        Cylinders of the same volume will have the same area, so it should be the same amount of aluminum?

        Maybe less, even, since the lid and bottom are thicker than the sides and on the taller can there’s less of that thick top/bottom

          Ignore things like the bevel, wall thickness, etc. Just calculating for a basic right cylinder, you can see how the surface area changes for different heights with a constant volume. I’ve outlined the standard dimensions of a can(inches). https://youtu.be/gL3HxBQyeg0

            I had a feeling it’d math out something like that if I opened my fat mouth, lol

            I do wonder if thickness of the walls or lid/bottom does have an effect, though, as there must be some reason they make these weird ass cans

          That can’t be true.

          Consider a cylinder cut in half, giving a circular cross section. Cover each new circular gap with new aluminum.

          Now you’ve enclosed the same volume in cylinders, with a different surface area.

            You also created 2 cylinders where once there was one, which is not what was being discussed. You even mention that you added material:

            Cover each new circular gap with new aluminum

            I could have said “2 cylinders of the same volume” but I felt context made that clear

              Yes I did say that I added material. That’s the point: you cannot do this transformation without adding material.

              But you’re saying this is only with two cylinders?

    Several years ago mountain dew had the following prices

    20 oz - $2

    1 liter - $2

    2 liter - $2

    1.5 liter - $1

    It wasn’t a sale, they had these prices on several stores for over a year.

      20oz are more expensive per volume because they sell faster. There’s less of a demand for larger sizes typically go flat too fast for people unless they’re having a party or something, and even in that case they don’t have the convenience of being able to drink from the bottle.

        Do you leave your soda uncapped or something? I buy almost exclusively 2 liter bottles and they very rarely go flat on me. I’ll drink one over the course of about 4 days.

          No. I never had any issues with larger soda bottles. I would usually buy the 1 or 1.5 liter bottles because they were usually the best deal.

          I did some sales work for one of the local soda distributors, and it was crazy how much better the 20oz bottles did in comparison to everything else.

          It was the same with energy drinks. Most people would buy single cans for $3 when they could get a 4 pack for $10 or a 12 pack for $20.

          We would usually just open the 12 packs at our accounts because the singles simply sold better.

    …do people think the tall can is bigger? If anything, I’ve always assumed that they were smaller 🤷‍♂️

        In my highschool psych class we actually went to an elementary school and did this experiment with the kiddos. It was a while ago but if I recall correctly, 9/10 times they thought tall = bigger. I bet some people never grow out of that mindset or at least at first glance our less smart brain goes “tall is big!”
