Estimate the volume of the solid that lies below the surface z = xy and above the following rectangle.
R =

(x, y) | 10 ≤ x ≤ 16, 0 ≤ y ≤ 4

(a) Use a Riemann sum with m = 3, n = 2, and take the sample point to be the upper right corner of each square.

Incorrect: Your answer is incorrect.


(b) Use the Midpoint Rule to estimate the volume of the solid.
