Question

The pressure increases by 1.0 x 104 N/m2 for every meter of depth beneath the surface of the ocean. At what depth does the volume of a Pyrex (bulk modulus 2.6 x 1010 N/m2) glass cube, 6.4 x 10-2 m on an edge at the ocean's surface, decrease by 5.8 x 10-10 m3?

I know that I need to use DeltaP=-B(DeltaV/V initial) but the wording is very weird so I'm having trouble with that.
