Well, you need to change 1 kg of steam at 180 degrees to an ice cube at 0 degrees. So, it is the heat it takes to lower the temp to 100 degrees, then the heat it takes to turn it to water, then the heat it takes to lower the temperature of water to 0 degrees, then the heat it takes to turn it to ice. If you add all of these up, you will get the total energy.
