When the height of a cuboid is reduced by 8cm, it just becomes a cube. At this time, the surface area is reduced by 128 square centimeters?
Reduce 8 cm to become a cube, which means that its length and width are equal. Set A. height as 8 + A. reduce 128 square cm in surface area to 8 x 4A = 128. You can get a = 4, then length and width are 4 cm, height is 12 cm, and volume is 4x4x12 = 192
