A cube bucket with a bottom area of 36 square decimeters contains 3 decimeters of water, When the water surface rises by 1 decimeter, find the height of the cuboid
1800 square centimeter = 18 square decimeter
When the water surface rises by 1 decimeter, the cuboid volume is 36 * 1 = 36 cubic decimeters
Height of cuboid = 36 △ 18 = 2 decimeters
