Rey recently bought some fish from a local pet store. A store worker told Rey that she should make sure there are not more than 2 fish per cubic meter. If Rey bought 28 fish to put in her tank that is a rectangular prism measuring 5 meters long by 2 meters wide, what is the minimum depth of the water needed in the tank in order for Rey to have enough water in the tank to meet the suggestion of the store worker? Provide an answer accurate to the nearest hundredth.
