Question

Ellie made a cube-shaped cardboard box with side-length s. The area of cardboard she used is given by the formula A = 6s2, where s represents the side length of the cube.

Which equation correctly solves the formula for s?

Answer 1

S= square A/6
 hope this helps 

Answer 2

The area of cardboard she used is given by the formula A = $6s^2$, where s represents the side length of the cube.

Now the question asks for the equation , which we can use to solve for s

it means

we have to solve for s

or in other words we have to isolate s

Now

A=$6s^2$

Divide both sides by 6

$\frac{A}{6} =s^2$

or

$s^2 =\frac{A}{6}$

Take square root on both side

$s =\sqrt{\frac{A}{6}}$

So this is the formula we can use to solve for s
