A square raft has dimensions 2.161m x 2.161m x 30cm. When a
91.7kg chest is placed on the raft, the raft floats with its top
surface 20cm above the water(10 cm is under water). The density of
the water is 1033 kg/m^3
What is the mass of just the raft?
How strong it the buoyant force being exerted by the
water on the raft?
How many crates can the raft hold (including the on on
it)?

A board that is 20.0 cm wide, 5.00 cm thick, and 3.00 m long has a density 379 kg/m3. The board is floating partially submerged in water of density 1000 kg/m3. What fraction of the volume of the board is above the surface of the water? 0.379 0.200 zero 0.621 The answer depends on which edge of the board is vertical. A 3.1-kg solid sphere, made of metal whose density is 2500 kg/m3, is suspended by a cord. When the...
