Any help would be appreciated!

This problem is based on Example #1 in {512.1 of Stewart (pg 833). Estimate the volume of the solid that lies above the square R = [0, 2] x [0, 2] and below the elliptic parabolid z = 13.8 {1:2 2.2y2. DivideR into four equal squares and choose the sample point to be the upper right corner of each square Rij- For your own benet, you should consider sketching the solid and the approximating recatngular boxes. unitsa
