Please respond to the boxes marked red. 

A box is formed by cutting squares from the four corners of a sheet of paper and folding up the sides.
a. Suppose the paper is 11"-wide by 15"-long. Let x represent the length of the side of the square cutout (in inches), and let V represent the
volume of the box (in cubic inches)
i. Write a formula that expresses V in terms of x.
V =
(11-2x)*(15-2x)*x
ii. If the cutout length increases from 0.7 to 2.1 inches, how much does the volume of the box change by?
