Question 1027384
w and L, the dimensions.
L=w+10, and w, again the same dimensions, using the given description.


Folding the flaps, the base of the box is (L-2*2)(w-2*2) inch^2 and the height is 2 inches.


This means the volume is  {{{2(L-4)(w-4)=528}}}.
Substitute for L, simplify the equation, and solve for w.


{{{2(w+10-4)(w-4)=528}}}
{{{(w+6)(w-4)=528/2}}}
{{{w^2+4w-24=264}}}
{{{w^2+4w-24-264=0}}}
{{{highlight_green(w^2+4w-288=0)}}}-----------Continue from here.....
