Great explanation. Hadn't considered doing all the work to get the function before taking the derivative. The way we were taught to do it was the opposite. First, we take the derivative of the volume function, and then we substitute in the values.
Using the power rule (I think) you take the power to the front so 3 and multiply 1/9 getting 1/27. You then take the power and subtract one getting h^2.

Thank you.
Thanks so much!
You’re welcome.
well-explained
Thank you.
how did the 1/27 go to a 1/9

dun diddly daaaaaaa dooooo
