For a cuboid, if its length increases by 3 cm and its width and height remain unchanged, its volume increases by 96 cubic centimeters; if its width decreases by 2 cm and its length and height remain unchanged, its volume decreases by 160 cubic centimeters; if its height increases by 2 cm, its length The sum and width remain the same, but its volume is increased by 80 cubic centimeters, find the surface area of the original cuboid.
