Formulas
These are formulas for materials that we have covered or are covering. I will try to keep this as up to date as possible for your use!
I found these surface area and volume formula formula sheets on https://www.tes.com/lessons/h9ywBdQ0wbZcVQ/finding-volume-with-a-cone-cylinder-and-sphere . They are lovely! She has a nice site with other possible resources for you to peruse.

Polygon Angle-Sum Theorem
This finds the measure of all of the interior angles of a polygon.
If you need to find one angle on a REGULAR polygon, divide the sum of the angles that we found by n, the number of sides. In this example, 720/6 = 120.
