Suppose you pour water into a container until it reaches a depth of 30.2 cm. Next, you carefully pour in a 14.8 cm thickness of olive oil so that it floats on top of the water. What is the pressure at the bottom of the container? Assume 1000 kg/m3 and 901 kg/m3 for the density of water and the oil, respectively.

pressure=weightwater/area + weightoil/area

= densitywater*g*h*area/A +densityoil*g*h*area/A

= 1000*.302*9.8+901*.148*9.8 Pascals
