Homework Statement
Jillian is getting ready to send a holiday package in the mail. The rectangular package has a square base and the sum of all the edges of the package measures 140 cm. What dimensions will produce a package with the largest possible surface area?
Homework Equations
Let x = widths and y = heights
The Attempt at a Solution
P=8x + 4y
140 cm = 8x +4y
-4y = 8x - 140 cm
y = -2 + 35 cm
This is as far as I can get. Am I supposed to solve for x? Please lend me a hint. Thanks a bunch!
