The pressure increases by 1.0 x 104 n/m^2 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 1010n/m^2) glass cube, 9.8 x 10^โˆ’2m on an edge at the ocean's surface, decrease by 7.5 x 10โˆ’10m^3? explain the formula beyond this point: p=1.0x10^4, b=2.6x10^10, l=9.8x10^โˆ’2, delta v=7.5x10^โˆ’10. at some point l needs to be cubed. why p is divided by delta v?
