A child is floating stationary in a inner tube in a swimming pool. the childs mass is 32 kg. the inner tube is completely submerged, just below the waterline, and 2.0 x 10^-2 m^3 of the childs body is submerged under the water. the density of the inner tube is 350 kg/m^3. the density of the water is 1.0 x 10^3 KG/M^3.
a) What is the volume of the inner tube?
