The figure shows a surface z = 4 cos(x) cos(y) and a rectangle R in the xy-plane. Z = 4 cos(x) cos(y) 77/4 (a) Set up an iterated integral for the volume of the solid that lies under the surface and above R. (Do not use symmetry.) dx dy -71/4 -TE/ 4 (b) Evaluate the iterated integral to find the volume of the solid
