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
2/-3 by using the formula y2-y1/x2-x1
Because the 18-gon is symmetrical, you can rotate it by 360/18 or 20 degrees. This is because when you rotate it by 20 degrees(to the left for explanation matters), any angle will now be in the position of its angle to its left.
