<p>I have been given a distance, an average flux, and a time period. How do I find the light energy emitted of a supernova over that time period?</p>

Your question seems interesting, but I feel like that a bit more details would not hurt, hence the close vote (which I am happy to retract once you edit). My main issue: Since you are mentioning a distance, you cannot be meaning the *overall* light emitted from the supernova. If so, you should also be having some kind of *observer area* (see [solid angle](https://en.wikipedia.org/wiki/Solid_angle)) over which you want to integrate.

Details can include examples of what you have studied to try to answer this. If you add context then answers can better address your needs. Also, you might apply [dimensional analysis](https://en.wikipedia.org/wiki/Dimensional_analysis) and see what happens, and while thinking about that, please mention the units of each of your givens, especially the flux. You may find a way to answer your own question in the process!
