The requested question did not include "In all possible scenarios", thus determining the volume of the sphere via physics calculation at the most average of conditions, is the most correct valid solution, absent further requirement parameters.

You're right in terms of grading a student's homework or whatever.

In research/publication/career these assumptions must be stated unless given.

But I was responding to:

The physicist’s answer would be correct anywhere, no matter the temperature or density of the fluid.

Which includes non-standard conditions.
