Find the pressure at a depth of 20 cm in brine of density `1.2 g//cm^3` .

Explanation

To find the pressure at a depth of 20 cm in brine with a density of 1.2 g/cm³, we can follow these steps:

### Step 1: Understand the formula for pressure
The pressure at a certain depth in a fluid is given by the formula:
\[ P = \rho g h \]
where:
- \( P \) = pressure (in Pascals or Newtons per square meter)
- \( \rho \) = density of the fluid (in kg/m³)
