A layer of water with depth $9.0\,\text{cm}$ has a layer of oil with depth $5.0\,\text{cm}$ above it in a measuring cylinder. The density of the water is $1000\,\text{kg m}^{-3}$ and the density of the oil is $800\,\text{kg m}^{-3}$. What total pressure is exerted on the base of the measuring cylinder by the oil and the water?
- A$390\,\text{Pa}$
- B$880\,\text{Pa}$
- C$1200\,\text{Pa}$
- D$1300\,\text{Pa}$
