\small\bold{\underline{\sf{\purple{Given}}}}

  • Surface area of a Cube = 216sq.cm

\small\bold{\underline{\sf{\red{To\:Find:-}}}}

  • The Volume of Cube.

\small\bold{\underline{\sf{\blue{solution:-}}}}

{\boxed{\rm{\red{Surface\:area\:of\:Cube= 6(side)^2}}}}

{\boxed{\rm{\green{Volume\:of\:cube = (side)^3}}}}

Now,

\implies\rm{Surface\:area\:of\:Cube = 6(side)^2}

\implies\rm{216sq.cm = 6(side)^2}

\implies\rm{(side)^2 = \dfrac{216}{6}}

\implies\rm{(side)^2 = 36}

\implies\rm{(side = \sqrt{36}}

\implies\rm{Side = 6cm}

Therefore,

\implies\rm{Volume\:of\:Cube = (side)^3}

\implies\rm{Volume\:of\:Cube = (6)^3}

\implies\rm{volume\:of\:Cube = 216cm^3}

Hence, The Volume of Cube is 216cm³

Given:-

  • Surface area of a Cube =216sq.cm

To Find:-

  • The Volume of Cube.

Solution:-

{\boxed{\rm{\purple{Surface\:area\:of\:Cube= 6(side)^2}}}}

{\boxed{\rm{\blue{Volume\:of\:cube = (side)^3}}}}

Now,

\implies\rm{Surface\:area\:of\:Cube = 6(side)^2}

\implies\rm{216sq.cm = 6(side)^2}

\implies\rm{(side)^2 = \dfrac{216}{6}}

\implies\rm{(side)^2 = 36}

\implies\rm{(side = \sqrt{36}}

\implies\rm{Side = 6cm}

Therefore,

\implies\rm{Volume\:of\:Cube = (side)^3}

\implies\rm{Volume\:of\:Cube = (6)^3}

\implies\rm{volume\:of\:Cube = 216cm^3}

Hence, The Volume of Cube is 216cm³
