20 vernier divisions coincide with 19 main scale divisions of a vernier. The smallest main scale division is 0.5 mm. When it measures the side of a cube the main scale and the vernier readings are 10 mm and 2, respectively. If the mass of the cube is 2.736 g, find out the density of its material keeping the significant digits only.
