The dimensions of a rectangular warehouse are to be determined for a company. It is known that the warehouse must accommodate a minimum of 1500 storage spaces with one cubic meters volume. The storage spaces will be used to hold pallets that are of dimensions 0.9 meters 0.9 meters 0.9 meters. Assuming that the horizontal and vertical aisle space multipliers a, b are 2 and 1, respectively, and that the I/O point for the warehouse is to be located in the middle of the east wall, determine dimensions of the warehouse with 3 levels of stacking.
