Feynman wouldn't dismiss that question. He'd overthink it. Someone once asked Feynman which way a top spinning sprinkler would spin if it was underwater and water was sucked through it instead of pushed out of it. He got into back and forth debates with other students. He ended up using the universities cooling pond for the cyclotron to actually run the experiment. https://en.wikipedia.org/wiki/Feynman_sprinkler https://en.wikipedia.org/wiki/Feynman_sprinkler So if you asked Feynman "How many ping pong balls would it take to fill a 747?" you wouldn't receive a "Why do you ask? What problem are you trying to solve?". Instead you'd find him trying to acquire a large 747 and a whole lot of ping pong balls in order to validate his initial guess.
