## Main Question or Discussion Point

How many days does it take for a perfect black-body cube (0.0100 m on a side, 30 degrees C) to radiate the same amount of energy that a one-hundred-watt light bulb uses in one hour?

If someone could point me in the right direction with how to go about solving this problem i would greatly appreciate it. I don't want to just be given the answer but shown how to go about solving this problem so that I can learn from the process. Thanks.
