This week I learned about how to figure out the volume of a cube when the sides are polynomials. You do this by taking said polynomial for example (3x^2+9) and timing it by three aka (Lengthxwidthxheight). Then you will get the product, you can do this by timing (3x^2+9) 3 times as said previously or doing two, getting that product and timing that last polynomial in, to get your final answer. You can do this with foil, my preferred choice.

My example:
