ms.smith has a new fish aquarium that measures 45.3 cm long, 23.4 cm wide and 28 cm high. She has had a problem with the fish jumping out of the tank. today she is cleaning and decides to fill the tank to a level that is 4cm from the top to see if that will help. how mmany litres of water does she need to fill her aquarium?
She will need to fill a volume of 45.3 by 23.4 by 24 (4 cm short of the 28cm)
Since 1 L of water = 1000 cm^3 of water
divide your answer by 1000 to get litres.
(I got about 25.5 L)
