Problem

The edge of a cube is measured using Vernier calipers.

9

divisions of the main scale equal

10

divisions of the Vernier scale, and

1

main-scale division equals

1\text{ mm}

. The main-scale reading is

10

divisions, and the first Vernier-scale division coincides with a main-scale division. The mass of the cube is

2.736\text{ g}

. Calculate the density in

\text{g}/\text{cm}^3

to the correct number of significant figures.
