$\huge\fbox\pink{A}\fbox\blue{n}\fbox\purple{S}\fbox\green{w}\fbox\red{E}\fbox\orange{r}$

$\Large{\blue{\tt{\underline{\underline{Given \ :-}}}}}$

☞ Volume of cube = 4096cm³

$\Large{\orange{\tt{\underline{\underline{To \ find \ :-}}}}}$

☯Total surface area = ?

$\Large{\purple{\tt{\underline{\underline{Solution \ :-}}}}}$

☞ Volume of cube = side³

☞ 4096 = side³

☞ side = ³√4096

⇢ side = 16cm

Now

☞ Tsa of cube = 6a²

☞ Tsa = 6×16×16

⇢ Tsa = 1536cm²
