You have an empty 3-liter container, a full 5-liter container with 50 degrees water, and a full 6-liter container with 90 degrees water.

Can you manage to get some 72 degrees water?

If the room temperature is 72 degrees, wait for all the water to become that temperature.

If the room temperature is over 72 degrees, wait for the 50-degree water to get to 72. If the room temperature is under 72, wait for the 90-degree water to get to 72.

In the latter instances, the 72-degree temperature of the water will be temporary, but then, so will be the temperature of any 72-degree water that you get by any method.
