उत्तर
\[\text { Volume of the given cube = 343 }m^3 \]
\[\text { We know that volume of a cube = (side })^3 \]
\[ \Rightarrow\text { (side })^3 = 343 \]
\[ \text { i . e . , side }= \sqrt[3]{343} = 7 m\]
\[ \therefore \text { Surface area of the cube = 6 }\times \text { (side ) }^2 = 6 \times (7 )^2 = 294 m^2 \]
