A boat is floating in a cylindrical tank of water, whose sides are vertical.
Inside the boat is an object that has a volume of 100 cm3. When the
object is taken from the boat and placed in the water, the water level in
the tank drops by a distance of n2 cm. The cross sectional area
of the tank is n1cm2. If the density of the object
is ρ = n3 ρwater,
what is n3? Note that n3 is unitless.
