By means of a hydrostatic balance, it is found that an iron cylinder and a glass cylinder of equal radii, when completely immersed in water, balance each other. If the specific gravities of iron and glass are 7.2 and 2.55 respectively, then determine the ratio of the lengths of the two cylinders.

The volume and mass of a piece of iron-aluminium alloy are 100cm^(3) and 588 g respectively. The specific gravities of iron and aluminium are 8 and 2.7 respectively. Calculate the ratio of the volumes of iron and aluminium on the alloy.

A piece of brass (Cu and Zn) weighs 12.9g in air. When completely immersed in water, it weighs 11.3g . Then relative densities of Cu and Zn are 8.9 and 7.1 respectively. The mass of copper in the alloy is
