 \large \underline \bold{Given}:-

\: \: \: \: \: \: \: \: \: \: \: \sf{Diagonal \: of \: Cube = 6\sqrt{3} \: m}

 \large \underline \bold{To \: Find}:-

\: \: \: \sf{Lateral \: surface \: area \: of \: Cube = \: ?}

 \large \underline \bold{Using \: Formulas}:-

\: \: \: \: \: \: \: \: \: \: \sf\boxed{\sf\red{Diagonal \: of \: Cube = \sqrt{3}a}}

\: \: \: \: \: \sf\boxed{\sf\red{Lateral \: Surface \: area = 4a^{2}}}

\: \: \: \: \: \sf{here \: \: ,}

\: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \sf{a = side \: of \: Cube}
