Find the average value of the function over the given solid. The average value of a continuous function (x, y, z) over a solid region

Find the average value of the function over the given solid. The average value of a continuous function ƒ(x, y, z) over a solid region Q is

where V is the volume of the solid region Q.

ƒ(x, y, z) = xyz over the cube in the first octant bounded by the
coordinate planes and the planes x = 4, y = 4, and z = 4
