1, cuboid volume = cuboid bottom area × cuboid height.
2. 1 liter = 1 cubic decimeter.
3. 1 decimeter = 10/0cm.
Solution: Bottom area of water tank =8 decimeters× 8 decimeters =64 square decimeters.
Water tank height = water tank volume ÷ water tank bottom area =384 cubic decimeter ÷64 square decimeter =6 decimeter =60 cm.
