Dimensions are given in a sequence of length, width and depth. The dimensions of a
box are described based on the opening of an assembled box, which can be located
on the top or the side.
The opening of the box is a rectangle; that is, it has two sets of parallel sides. The longer
of the two sides is considered its length, the shorter of the two sides is considered its
width. The side perpendicular to length and width is considered the depth of the box.
