Have you tried to calculate this yourself?
This sounds like a study question and it's missing some pertainent info to actually come up with an answer, there must be some AC / heat
Use article 220 and see what you come up with.

Hold on while I get right on that...
What is "40 receptacles continuous duty" and how much continuous load?
What is the actual lighting load?
What is a "heavy-duty" multi-outlet assembly?
If this is an exam or homework question, you must have forgotten a good deal of the question.
If this is an actual project you will need MUCH more information before coming up with any meaningful load figures...
