Answer 2

Question :-

The Surface Area of a Cube is 2,568 sq. m. Calculate its Side.

Solution :-

Let the Length of each Side of the Cube be a m.

Then, its Total Surface Area = $\bold {(6a^2)\:m^2}$

But, the Total Surface Area of the Cube = $\bold {2,568\:m^2}$

∴ $\bold {6a^2 = 2,568 m^2}$

$a^2 = \bold {428}\\\\Therefore, \bold a = \sqrt{428} = \sqrt{4 \times 107} \\\\= \bold {2\sqrt{107}\:m\: or \:20.69 \:m}$

Hence,

The Length of each Side of the Cube = $\bold {2\sqrt{107}\: m \:or \: 20.69\: m}$
