**Outcome:** Find the absolute maximum or minimum value of a quantity subject to given constraints.

**MATH 2413: Calculus I – Activity 10**

1. Postal regulations limit the girth plus length of a box to 108 inches (“girth” is the perimeter of the smallest end). What are the dimensions of the largest box with a square end that can be mailed?
   
   (a) Let \( x \) be the length of one side of the square end and \( y \) the length of the longer side. Label these below.

   - *Diagram Description:* The image shows a three-dimensional box with a square end. The sides of the square are labeled as \( x \), and the longer side of the box is labeled as \( y \).

(b) What quantity does this problem ask to maximize? Find a formula for this quantity in terms of \( x \) and \( y \).

(c) The largest such box’s girth plus length equals 108 inches. Write this as an equation involving \( x \) and \( y \).

(d) Use your equation from (c) to rewrite your formula from (b) as a function of \( x \) only.

(e) Based on what \( x \) represents in this problem, what is the domain of this function?

(f) Use Calculus to find the dimensions of the largest such box that can be mailed. Include units.
