The length of the aquarium is 80 cm, the width is 45 cm, and the height is 55 cm. How many liters of water should be poured into it so that its level is 10 cm below the upper edge of the aquarium?

1) 45 × 80 × 55 = 149000 (cm ^ 3) – the volume of the entire aquarium
2) 10 × 45 × 80 = 38000 (cm ^ 3) – the amount of space that should not be filled
3) 149000-38000 = 111000 (cm ^ 3) – you need to pour water
Answer: 111000cm ^ 3
