Explanation:
First, you should get to know Pascal's triangle. Here's a small portion of it up to 6 lines. Basically you're just adding the numbers that are beside each other, then writing the sum below them. (For example,
1
+
2
in the third line equals to
3
in the fourth line.) If you want a better explanation for that, feel free to do some more research on it.
Answer:

Step-by-step explanation:
The area of cardboard she used is given by the formula A = , 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=
Divide both sides by 6
or
Take square root on both side
So this is the formula we can use to solve for s
