Quick G-Chem question

Hey guys, I just had a question from the Dat destroyer chem section. Sorry if it's a really simple question, chem is definitely not my strength. This is number 47 on pg. 124. The question is: A gas is compressed from 40 liters to 16 liters at a constant pressure of 4.0 atm. If 10 KJ of energy is released as heat, find the work done for this process.

Using the W=-P(delta)V formula I come up with 96.1 l*atm, the correct answer. I was just wondering: what is the significance of the 10 KJ of energy released?

I guess they threw in the heat change as a curveball. Maybe the question was "find the change in internal energy for this process" and he changed it to find the work.
