This could be a mass or a volume problem, actually there are some other things that could limit the problem statement but those are the obvious ones. But the problem is too general to solve. It really just depends on what you want to do with the ping pong balls and the airplane after you filled the airplane. That’s the critical piece of information that’s missing that should be provided. Otherwise you end up with a bunch of solutions that technically meet the problem parameters but don’t actually solve a real problem
