Question

The formula represents the surface area S of a cube with side lengths x.

Answer 1

Answer:

$s = 6 {x}^{2} \\ {x }^{2} = \frac{s}{6} \\ x = + - \sqrt{ \frac{s}{6} } \\ x = \frac{ \sqrt{s} \times \sqrt{6} }{ \sqrt{6} \times \sqrt{6} } \\ x = \frac{ + - \sqrt{6s} }{6}$

the answer is 4 th option

Answer 2

The answer is the last one
