There are two cans of food are sitting on a kitchen counter. The same pressure is exerted on the table by each of the weights of the cans; however the cans are not identical and the densities of the contents are not identical. The radius of can 1 is r1 = 0.045 m and the radius of can 2 is r2 = 0.025 m. The density of can 1 is ρ1 = 810 kg/m3, the density of can 2 is ρ2 = 980 kg/m3, and the height of can 1 is h1 = 0.18 m.
This scenario is absolutely possible because the pressure equals force of gravity divided by area, whereas the force of gravity is area times height times density times acceleration due to gravity.
