For a cuboid, if the length is reduced by 5cm, the volume will be reduced by 240cm**3, if the width is reduced by 4cm, the volume will also be reduced by 240cm**3, if the height is reduced by 3cm, the volume will still be reduced by 240cm**3, find the surface area of the original cuboid.
一个长方体，如果长减少5cm，体积就减少240cm**3，如果宽减少4cm，体积也减少240cm**3，如果高减少3cm，体积还是减少240cm**3，求原来长方体的表面积．
