We must prepare the aquarium to put the fish in. How many litres of water do we need? We know outside dimensions of the aquarium. The glass is 1cm thick. We should fill the aquarium in 90% with water. Water poured directly from taps is not healthy for fish. It should be settled in some containers for at least 24 hours. How many 0.8 litre jars full of water will we need?
