volume = s * (20 - 2s) * (15 - 2s) = 300 s - 70 s^2 + 4 s^3
the 1st derivative will show the relative max/min
dv/ds = 300 - 140 s + 12 s^2
... set equal to zero and check for max/min , by plugging s into the volume equation
An open topped box is constructed from a 20 inch by 15 inch piece of cardboard by cutting equally sized squares from each corner and folding up the resulting flaps.
