उत्तर
\[\text { Volume of the given cube = 216 }{dm}^3 \]
\[\text { We know that volume of a cube = (side ) }^3 \]
\[ \Rightarrow (\text { side ) }^3 = 216 \]
\[\text { i . e . , side = } \sqrt[3]{216} = 6 dm\]
\[ \therefore \text { Surface area of the cube = 6 }\times \text { (side ) }^2 = 6 \times (6 )^2 = 216 {dm}^2\]
