The temperature at a point is given by T = xyz. Find the average temperature in the cube
with opposite corners at (0,0,0) and (2,2,2).
Determine the average value of F(x, y, z) = xyz throughout the cubical region D
bounded by the coordinate planes and the planes x = 2, y − 2, z = 2 in the first octant.
