Pressure, Density, and Atmospheric Pressure

[kallisti]

Homework Statement

What is the absolute (total) pressure at the depth of 15 m below the surface of the sea. Assume density of seawater is 1.03 g/cm3 and g=10 m/s2. Give answer in kPa. Use atmospheric pressure is 101 kPa.

Homework Equations

P = F/A
P₁V₁=P₂V₂

The Attempt at a Solution

i don't know how to solve it because neither of the formulae my teacher gave me have atmostpheric pressure or density and the problem doesn't have volume please help!

Pressure in this case doesn't depend on volume, it just depends on gravity, density and the height of the fluid column above you. You've probably seen the equation before- p=d*g*h.

The total, then, is just that plus atmospheric pressure.
