    Hello there,

    A good starting point would be to calculate the total pressure (including atmospheric pressure) acting on the bubble at the surface and at the  20 m depth. The pressure of the gas inside the bubble in each scenario must equal said pressure. You can then use the ideal gas law,  PV = nRT , to calculate the volume at the  20 m depth.

    I hope that this has been helpful.
