This is an incomplete question, here is a complete question.
The bulk modulus for bone is 15.0 (GPa). If a diver-in-training is put into a pressurized suit, by how much would the pressure have to be raised (in atmospheres) above atmospheric pressure to compress her bones by 0.130% of their original volume?
Answer : The change in pressure will be, 
Explanation : Given,
Bulk modulus = 
Change in volume = 0.130 % of original volume
Let the original volume be, V
So, Change in volume = 
Formula used for change in pressure is:

Now put all the given values in this formula, we get:


Thus, the change in pressure will be,
