One day when you come into physics lab you find several plastic hemispheres floating like boats in a tank of fresh water. Each lab group is challenged to determine the heaviest rock that can be placed in the bottom of a plastic boat without sinking it. You get one try. Sinking the boat gets you no points, and the maximum number of points goes to the group that can place the heaviest rock without sinking. You begin by measuring one of the hemispheres, finding that it has a mass and a diameter of . What is the mass of the heaviest rock that, in perfectly still water, won't sink the plastic boat?
You need to determine the density of a ceramic statue. If you suspend it from a spring scale, the scale reads . If you then lower the statue into a tub of water, so that it is completely submerged, the scale reads . What is the statue's density
