Ask for video: a cuboid glass tank bottom surface is a circumference 60cm square, pour 8L water to fish tank, what is the height of water?

Bottom side length: 60 / 4 = 15 cm
The bottom area is: 15 * 15 = 225 square centimeters = 2.25 square decimeters
The water height is: 8 / 2.25 = 3.6 decimeters
