Water was poured into an aquarium 16 ”long, 10” wide and 4 ”high, the level of which was 20 cm below the top edge of the aquarium. How many liters of water were poured into the aquarium?

Find the volume of water in the aquarium, for this you need to multiply the width of the aquarium by the length and multiply by the height of the poured water.
By condition, it is known that the width of the aquarium is a = 10 dm.
By condition, it is known that the length of the aquarium is b = 16 dm.
By condition, it is known that the height of the aquarium is 4 dm, but the water was poured 20 cm or 2 dm less. So the height of the water c = 4 dm – 2 dm = 2 dm.
Let us now find the volume of water: V = a * b * c = 10 * 16 * 2 = 320 dm³.
Since 1 dm³ = 1 liter, then 320 dm³ = 320 liters.
Answer: 320 liters of water are poured in the aquarium.
