Units And Measurements

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 1 mm). The
main scale reads 10 mm 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.
