4. (a) How many surface integrals would the surface integral I IS F" - d5" need to be split up into, in order to evaluate the surface integral I IS F, - (is; over S, where S is the surface bounded by the coordinate planes and the planes :6 = 10, y = 5, and z = 1 and 1:" = (mye'wyz'l, yez)? Set up one of the surface integrals over a non-zero plane (such as :c = 10, y = 5, or z = 1). If it is possible to evaluate the surface integral over the plane you chose, evaluate it. If not, explain why. (b) Is there an easier way to compute this surface integral? Why or why not?
