The edge of a cube is measured using a vernier callipers. [`9` divisions of the main scale is equal to `10` divisions of the vernier scale and `1` main scale dividsion is `1 mm`]. The main scale division reading is `10` and `1st` division of vernier scale was found to be coinciding with the main scale. The mass of the cube is `2.736 g`. Calculate the density in `g//cm^3` upto correct significant figures.
