As a human I couldn't solve it. I missed the key insight that we can calculate the side surface area and it will be the same if it is rolled out into a rectangle. It might make more sense to give it math problems with enough hints that a human can definitely do it. For example you might try saying: "Here is an enormous hint: the side surface area is easy to calculate when it is rolled up and doesn't change when it is unrolled into a rectangle, so if you calculate the side surface area when rolled up you can then divide by the known length to get the width." I think with such a hint I might have gotten it, and ChatGPT might have as well. Another interesting thing is that when discussing rolls of tape we don't really talk about inner diameters that much so it doesn't have that much training data. Perhaps a simpler problem could have been something like "Imagine a roll of tape where the tape itself has constant thickness x and length y. The width of the tape doesn't matter for this problem. We will calculate the thickness. The roll of tape is completely rolled up into a perfectly solid circular shape and a diameter of z. What is the formula for the thickness of the tape x expressed in terms of length y and 'diameter of the tape when rolled up in a circle' z? In coming up with the formula use the fact that the constant thickness doesn't change when it is unrolled from a circular to a rectangular shape." With so much handholding, (and using the two-dimensional word circular rather than calling it a cylinder and rectangular prism which is what it really is) many more people could apply the formula correctly and get the result. But can ChatGPT? I just tested it, this is how it did: https://chat.openai.com/share/ddd0eef3-f42f-4559-8948-e028dabed603 https://chat.openai.com/share/ddd0eef3-f42f-4559-8948-e028da... I can't follow its math so I don't know if it's right or not but it definitely didn't go straight for the simplified formula. (pi times half the diameter squared to get the area of the solid "circle" and divide by the length to get the thickness of the tape.)
