Question 1126650
-----------------------------------------------------------------------
A box is formed by cutting squares from the four corners of a sheet of paper and folding up the sides. However, the size of the paper is unknown! 
The function f determines the volume of the box (in cubic inches) given a cutout length (in inches). 
----------------------------------------------------------------------


Dimensions for the sheet of paper:  L and w

Side length of square corner to remove:  x, which is also the box height.


Box base area:  {{{(L-2x)(w-2x)}}}


Volume for the box:  {{{highlight(x(L-2x)(w-2x))}}}



The listed questions are just arithmetic and algebra based on the volume formula.
