A cube of material with density 3,105 kg/m³ is placed on a smooth, level surface. A
very thin layer of fluid on the surface prevents air from getting underneath it. If the
ambient pressure is 101 kPa and each side of the cube has length 0.6 m, calculate the
force in Newtons that must be exceeded to lift the cube straight up off the surface. (1
kPa = 1000 Pa)
