a cube of glass of 5cm sides and mass of 306g has a cavity inside it .If the density of glass is 2.55g/cm^3, what is the volume of the cavity​



Answer :

Explanation:

volume of the cube is 5 x 5 x 5 = 125 cm^3

Mass SHOULD be   125 cm^3 * 2.55 g / cm^3 = 318.75 g

Given it is only 306 g

   the volume of glass is   306g / 2.55 g/cm^3 = 120 cm^3

      the remaining 5 cm^3 is the cavity
