The density of the copper block is  8.92 g/cm³

  • The density is also called volumetric mass density which is used to measure the mass of a substance.
  • Density is intensive property that means it does not depend upon the size or amount of the substance.

        The given values are

        The mass of the copper = 1896 g

         The dimensions of block = 8.4 cm ,5.5 cm ,4.6 cm

         The formulae of density is

         Density = Mass/ Volume

         Volume of a rectangular block = length ×breadth× height

                                                   = 8.4 cm× 5.5 cm ×4.6 cm

                                                   = 212.52 cm³

         By substituting all the values in given formulae

         Density of copper block = 1896 g /  212.52 cm³

                                                   = 8.92 g/cm³

By using the density formulae we can easily calculate the mass of        substance or volume of a substance.
