If the length of a cuboid is reduced by 3cm, it becomes a cube, At this time, the surface area is reduced by 96cm, what is the volume of the original cuboid?

If the length of a cuboid is reduced by 3cm, it becomes a cube, At this time, the surface area is reduced by 96cm, what is the volume of the original cuboid?

Cuboid width and height = 96 / 12 = 8cm
8 * 8 * 11 = 704 cubic meters
