Question 391080
<font face="Garamond" size="+2">


If you cut x by x squares from each corner and fold up the sides, you will have a box that measures 6 - 2x by 7 - 2x by x, hence the volume is:


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ V(x)\ =\ (6\ -\ 2x)(7\ -\ 2x)x]


Multiply it out to get a third degree polynomial and then put it in to your graphing calculator.

*[tex \LARGE e^{i\pi} + 1 = 0]
My calculator said it, I believe it, that settles it
