The side of a cube is measured by vernier callipers (`10` divisions of a vernier scale coincide with `9` divisions of main  scale, where `1` division of main scale is `1mm`). The main scale reads `10mm` and first division of vernier scale coincides with the main scale. Mass of the cube is `2.736 g`. find the density of the cube in appropriate significant figures.
