Each side of a metallic cube of mass $\displaystyle 5.580$ kg is measured to be $\displaystyle 9.0$ cm. Keeping the significant figures in view, the density of the material of the cube can be best expressed as $\displaystyle \mathrm{X} \times 10^3 \mathrm{~kg} \mathrm{~m}^{-3}$, where the value of X is :
