Please help me with 4 and 5.
2. Let's make an open-topped box from an 8.5 x 11-inch sheet of paper by cutting squares of length from
cach corner and folding up the sides. Then let's tape the four squares together to make a pencil holder,
which is a box without a top or bottom but will still hold pencils if it sits on a desk. See pictures below.

(a) What's the maximum combined volume of an open-topped box plus a pencil holder that we can achieve?
Hint: What domain makes sense for r in this problem? How do we find a maximum value on such a domain?
(b) What do we make if we maximize the combined volume, i.e., what does your solution to (a) result in?
