Suppose you are given a problem to find the dimensions for the maximum volume of a cube given the surface area. These problems involve 2 equations, taking the derivative and setting it equal to zero (local minimum or maximum) and substituting the 2nd equation to find the parameters. However, suppose I wanted to know the dimensions with the minimum volume, how can I go about doing that? Clearly using the same method will result in a maximum? When doing these, since setting a derivative to zero gives a local max or min, how is one to know which one will be found?
