Volume of cube inside water
$\begin{array}{rl}& =\left(\frac{\text{ Denslty of cube }}{\text{ Denslty of water }}\right)\times \text{ Volume of cube }\\ & =\frac{\text{ Mass of cube }}{\text{ Denslty of water }}\\ & =\frac{400\mathrm{gm}}{1\mathrm{gm}/{\mathrm{cm}}^3}\\ & =400{\mathrm{cm}}^3\end{array}$
Volume of cube outside water
$\begin{array}{rl}& =\text{ Volume of cube }-\text{ Volume of cube inside water }\\ & =1000{\mathrm{cm}}^3-400{\mathrm{cm}}^3\\ & =600{\mathrm{cm}}^3\end{array}$
