If the height of a cuboid is 2 cm, the surface area will be reduced by 24 square cm. The rest is just a cube. What is the surface area of the original cuboid?
If the height of a cuboid is 2 cm, the surface area will be reduced by 24 square cm, and the remaining part is just a cube: it shows that the bottom of the original cuboid is square, and if the side length of the bottom is x, then 2x * 4 = 24, x = 3 cm, so the height of the cuboid is 3 + 2 = 5 cm
The surface area of the original cuboid is: 5 * 3 * 4 (4 sides) + 3 * 3 * 2 (2 bottom surfaces) = 78 square centimeters
