2) Change the order of integration for the triple integral (x² + In(y) + z)dx dy dz so that you are integrating with respect first to z, then x, then y. You do not need to evaluate the integral.

A soda can has a volume of 25 cubic inches. Let x denote its radius and h its height, both in inches. a. Using the fact that the volume of the can is 25 cubic inches, express h in terms of x. b. Express the total surface area S of the can in terms of x.
