If the height of a cuboid is reduced by 2 cm, it becomes a cube and its surface area is reduced by 48 square cm

Because the height is reduced by 2cm, it is a cube, so the bottom is square. Then the length of the bottom is 48 / 4 / 2 = 6cm, the height is 6 + 2 = 8cm, and the volume is 6 * 6 * 8 = 288cm3
Attachment: original surface = 6 * 8 * 4 + 6 * 6 * 2 = 264 square cm
A: slightly
