External volume (without counting hollow part) = 36*25*16.5 = 14850 cc

Internal dimensions of box:
=> 36-2(1.5) = 33cm
=> 25-2(1.5) = 22cm
=> 16.5-2(1.5) = 13.5cm
Volume of hollow part in box = 33*22*13.5 = 9801 cc

Box is open, therefore top part must be removed.
Volume of top part = 36*25*1.5 = 1350 cc

Therefore, volume of box = 14850-9801-1350 = 3699 cc

Weight of box = 3699*15 = 55485g = 55.485 kg
