SUMMARY
The absolute pressure at the bottom of a container filled with water and oil can be calculated using the formula P = ρgh + P(atmospheric). In this case, a 20.0 cm depth of water is topped with a 29.0 cm layer of oil with a specific gravity of 0.800. The correct calculation requires converting all measurements to meters and summing the contributions of both fluids without subtracting their depths. The final absolute pressure should be recalculated to ensure accuracy, as initial attempts yielded a discrepancy greater than 10%.
