A cubical box 24.85 cm on each side is immersed in a fluid. The pressure at the top surface of the box is 109.47 kPa and the pressure at the bottom surface is 112.03 kPa. What is the density of the fluid?

i used
P2=P1+pgh

P2-P1 divded by gh = p
i used this to solve for p, when i checked my answer, it was wrong.

any help?

Looks okay to me. Did you get 1050 kg/m^3 ?

$$p = p1-p2 / g*h$$
