Find the maximum volume of an open box made from a 3' by 8' rectangular sheet with equal squares cut fromt he 4 corners:
The volume is `V=(3-2x)(8-2x)x`
** Each length has a segment of length x cut from both corners; the height of the box will be x **
To find the maximum we take the derivative with respect to x.
`V=4x^3-22x^2+24x` after expanding...
