If the height of a cuboid is reduced by 2 centimeters, it becomes a cube, whose surface area is known to be 24 square centimeters less than the original. Find the volume of the original cuboid. (Click for ideas: Since the bottom of the cuboid is a square, the areas of its four sides are equal.).
将一个长方体的高减少2厘米就变成了一个正方体，已知它的表面积比原来减少了24平方厘米．求原长方体的体积．(思路点击：由于长方体的底面是正方形，所以它的四个侧面的面积相等．)．
