Determine the density of the liquid that is pressing 700 kPa at the bottom of the cavity. The depth of the depression is 70 meters

Determine the density of the liquid that is pressing 700 kPa at the bottom of the cavity. The depth of the depression is 70 meters. write down what kind of liquid

P = rgh,
Where r is the density of the liquid,
G – acceleration of gravity, 10m / s ^ 2
H – depth.
P- Pressure, 700kPa = 700000Pa
r = P / gh
r = 700000Pa / 70m * 10m / s ^ 2 = 1000kg / m ^ 3
This liquid is water
