1. The problem statement, all variables and given/known data I am currently taking calc III and we have starting getting into double and triple integrals. I was wondering what you are actually doing when you take a double or triple integral? And what the difference is. I understand that you find area with a single integral and find volume with a double, but you can also find find volume with a triple integral. While there are some things such as mass that can only be found using a triple integral. I guess my quest is: what are you actually doing to an object when you take multiple integrals of it?
