In a cylindrical container water is filled up to a height of h_(0)=1.0m . Now a large number of small iron balls are gently dropped one by one into the container till the upper layer of the balls touches the water surface. if average density of the contents is rho=4070 kg//m^(3) , density of iron is rho_(i)=7140kg//m^(3) and density of iron is rho_(0)=1000kg//m^(3) find the height h of the water level (in S.I. units) in the container with the iron balls.
