    B)         \[13.824cu.cm\]

    C)         \[1.3824\times {{10}^{8}}cu.cm\]

    D)         \[1.3824\times {{10}^{4}}cu.cm\]

    Correct Answer: A

    Solution :

    Side of cubical box = 2.4 m \[\therefore \] Volume\[\text{=(side}{{\text{)}}^{\text{3}}}\text{=(2}\text{.4 m}{{\text{)}}^{\text{3}}}\] \[=13.824\text{ }{{m}^{3}}=13.824\times {{10}^{6}}\text{ }c{{m}^{3}}\] \[=1.3824\times {{10}^{7}}c{{m}^{3}}\]
