A Rubik's cube is, well, a cube.
That means that each if its faces is a square, a quadrilateral with four right angles and four sides if the same length.
If the length of one side is x,
4x=22.2
x=5.55 centimeters.
Hope this helps!
Your fortune is "All your hard work will finally pay off."

1. It is a quadratic equation.
Explanation:
A quadratic equation is any equation that can be rearranged in standard form (ax^2 + bx + c). That equation can be rewritten as -x^2 + 1, where a is -1, b is 0, and c is 1.
2. 4x^2, 3x, and 5.
Explanation:
A quadratic term is ax^2 in the formula ax^2 + bx + c. A linear term is bx in the formula, and a constant is c in the formula.
I’m pretty sure it’s h because the lines meet in the x axis
