Expert Solution
Step 1

The volume under the surface:

Assume that f(x,y) is continuous in the xy- plane over a rectangular region as illustrated above. The volume beneath the surface is represented by the double integral I=f(z). By slicing the three-dimensional region like a loaf of bread, we can calculate the volume. Assume the slices are perpendicular to the y-axis.
