A light hollow cube of side length $\displaystyle 10$ cm and mass 10g, is floating in water. It is pushed down and released to execute simple harmonic oscillations. The time period of oscillations is $\displaystyle y \pi \times 10^{-2} \mathrm{~s}$, where the value of $\displaystyle y$ is (Acceleration due to gravity, $\displaystyle \mathrm{g}=10 \mathrm{~m} / \mathrm{s}^2$, density of water $\displaystyle =10^3 \mathrm{~kg} / \mathrm{m}^3$ )
