A) \[64{{m}^{3}}\]
B) \[216{{m}^{3}}\]
C) \[512{{m}^{3}}\]
D) \[196{{m}^{3}}\]
Correct Answer: B
Solution :
Let length of side of the cube be a then volume of cube\[={{a}^{3}}\] Also surface area of cube\[=6{{a}^{2}}\] Given, volume of cube = surface area of cube \[{{a}^{3}}=6{{a}^{2}}\] \[\Rightarrow \] \[a=6m\] Thus, volume of the cube\[={{(6)}^{3}}=216{{m}^{3}}\]
