Required information The closed layered box in the image has square horizontal cross sections everywhere. All fluids are at $$20^{?}\mathrm{C}$$. The density of oil is $$891\mathrm{kg}/{\mathrm{m}}^3$$ and the density of water is $$998\mathrm{kg}/{\mathrm{m}}^3$$. Estimate the gage pressure of the air if the hydrostatic force on panel $$AB$$ is $$113\mathrm{kN}$$. $$\mathrm{Pa}$$ Required information The closed layered box in the image has square horizontal cross sections everywhere.
