I'm not sure what this is asking to find, and have been getting it wrong. I've currently been trying to solve it for the Thermal Energy.

A heat engine operating between energy reservoirs at 20 C and 600 C has 30% of the maximum possible efficiency. How much energy must this engine extract from the hot reservoir to do 1000 J of work?
