The bottom of a cuboid pool is 15 decimeters long and 6 decimeters wide. How many liters of water do you need to fill the pool with water four decimeters high

Cuboid volume = base x Height x width
15x6x4 = 360 cubic decimeter = 360 liter

A cuboid pool is 15 decimeters long, 8 decimeters wide and 12 decimeters deep. How many liters of water do you need to inject 6 decimeters deep into the pool?

Length * width * water depth 15 decimeters * 8 decimeters * 6 decimeters = 720 cubic decimeters
Because: 1 cubic decimeter = 0 liter
So: 720 cubic decimeters = 720 liters
So it takes 720 liters of water to pour 6 decimeters of water into the pool

When 152l water is injected into a cuboid tank, the water surface rises by 4 decimeters. The bottom area of the tank is ()

152 / 4 = 38 square decimeters
