\green{\therefore{\text{Side\:of\:square=8\:cm}}}

\orange{\bold{\underline{\underline{Step-by-step\:explanation:}}}}

\green{\underline \bold{<klux>GIVEN</klux> :}} \\ : \implies \text{T.S.A \: of \: cube = 384 \:{cm}}^{2} \\ \\ \red{\underline \bold{To \: Find :}} \\ : \implies \text{Side \: of \: cube = ?}

• ACCORDING to given QUESTION :

\bold{As \: we \: know \: that } \\ \circ \: \text{T.S.A \: of \: cube =} 6 \times \text{{side}}^{2} \\ \\ \text{Putting \: given \: values} \\ : \implies 384 = 6 \times {a}^{2} \\ \\ : \implies \frac{384}{6} = {a}^{2} \\ \\ : \implies {a}^{2} = 64 \\ \\ : \implies {a}^{2} = {8}^{2} \\ \\ \bold{As \: we \: know \: that \: both \: side \: power }\\ \bold{are \: same \: so \: bases \: are \: also \: same}\\ \green{: \implies a = 8 \: cm} \\ \\ \green{\therefore \text{Side \: of \: square = 8 \: cm}}\\\\ \bold{Some\:formula's\:related\:to\:this\:topic}\\ \\ \circ\:\text{C.S.A\:of\:cube=4}\times\:side^{2}\\\\ \circ\:\text{Volume\:of\:cube=side}^{2}
