Problem

The diameter of a small steel sphere is measured as

6.24\,\text{mm}

and its mass is found to be

1.8\,\text{g}

. Treating the sphere as perfectly spherical, calculate its density in

\text{kg}\,\text{m}^{-3}

and report the answer with the properly limited significant figures. Show all stages of unit conversion, numerical computation and rounding.
