Explanation:
Assuming the liquid to be water ,
the density
of water is :
Buoyant force exerted by a liquid on an object with
of it's volume immersed is :

where ,
is the buoyant force
is the density of the liquid
is the acceleration due to gravity
Thus at equilibrium:

from these , we get the density of brass to be 
which is not possible
