Aquarium length 80 cm width 50 cm height 40 cm How many liters of water can be poured into the aquarium.

Method 1.

We find the full volume of the aquarium.

80 * 50 * 40 = 80 * 2000 = 160,000 cm3

We translate into liters.

160,000 / 1,000 = 160 HP

Method 2.

First, let’s convert the size of the aquarium to decimeters.

Since 1 dm = 10 cm, we get:

80/10 = 8 dm.

50/10 = 5 dm.

40/10 = 4 dm.

Find the volume of the aquarium.

8 * 5 * 4 = 40 * 4 = 160 dm3

Since 1 dm3 = 1 liter, this means that 160 liters of water can be stored in the aquarium.

Answer: 160 l.
