Given data
*The given height under the ocean surface is h = 12.3 m
*The given density of ocean water is D = 1025 kg/m^3.
*The value of the acceleration due to the gravity is g = 9.8 m/s^2
The formula for the pressure on a fish 12.3 m under the ocean surface is given as
[tex]p=Dgh[/tex]Substitute the known values in the above expression as
[tex]\begin{gathered} p=(1025)(9.8)(12.3) \\ =1.23\times10^5\text{ Pa} \\ =1.21\text{ atm} \end{gathered}[/tex]
