So the volume in one case is expressed in meters and in the other case it is expressed in liters. You might know how many liters are in a cubic meter or you might look it up. You can ask Google "How many liters are there is a cubic meter?" I'm a Mac user so I asked Siri. Once you know the number of liters in a cubic meter convert the volume of the tank to liters. Can you solve the problem now? Write back if you need more assistance. Penny
