>how many jellybeans fit inside a 747 aircraft
One 747-sized jellybean, liquified for easy insertion.
As with the pizza example, basic area or volume calculations aren't too hard if you accept approximations of the required inputs. But I'm skeptical of their value as a measure of employee resourcefulness.
The ability to figure out how much of x fits into y should be assumed, at least for jobs requiring a high school degree. It's not as if, say, an Amazon warehouse ever got backed up because workers kept trying to put orders into boxes that were too small, leaving managers wishing for employees with better volume-calculation skills.
