You place a glass beaker, partially filled with water, in a sink. The
beaker has a mass of 517 g and an interior volume of 280 cm3. You now start to fill the sink with water and find, by experiment, that if the beaker is less than half full, it will float; but
if it is more than half full, it remains at the bottom of the sink as the water rises to its brim. What is the density of the material of which the beaker is made?
Fb = pVg
P2 = P1 + Pgh
