If the length of a cuboid is reduced by 3 centimeters, but the width and height remain the same, its volume will be reduced by 48 cubic centimeters. If the width is increased by 4 cm, the length and height remain the same, and its volume is increased by 120 cubic centimeters. If the height is increased by 5 cm, the length and width remain the same, and its volume is increased by 400 cubic centimeters. What is the surface area of the original cuboid? ?
