Cube point picking is the three-dimensional case of hypercube point picking.

The average distance from a point picked at random inside a unit cube to the center is given by

			(1)
			(2)
			(3)
			(4)

Similarly, the average distance from a point picked at random to a fixed corner is given by

			(6)
			(7)
			(8)
			(9)

where is the -box integral.

The average distance from the center of a unit cube to a given face is
