2. (1 Point} Problem 2 (Evaluated for mathematical work - accuracy and notational neatness) Suppose you are given a. solid volume W. You do not have the full picture of this volume: only the projections of W into the yz-plane and the Iy-plane (both shown below): Write {but do not evaluate!) an expression to nd the average value of the function f(:1:, y,z} = z? on W. (Hint: Your answer should be written in terms of two nil-evaluated iterated triple integrals. I would prefer them both in the same integration order if possible - dz dy (12 might be a good one.)
