Fluid Mechanics. Volume of a bubble.

[tommooooooo_7]

I was doing some online physics tests with my friend because we were bored and we both got stuck on this question, I was wondering if anyone might be able to help.

A diver at 50metres under the sea (1.02 density) releases bubbles 1cm^3 in volume. What will the volume be when the bubbles reach the surface?

(no temperature mentioned in the question)

Any help appreciated,
Many thanks.

Wouldn't this just be a simple case of P1V1 = P2V2, where 1 = the initial conditions, i.e. a volume of 1 and pressure of 6 atmospheres (one atmosphere for every ten metres of depth and an obvious additional atmosphere so we're working with the total pressure), and P2 = 1. Therefore I get V2 = 6.
