The United States Postal Service ships a package under large-package rates if the sum of the Tength and the girth of the package is greater than 84 inches and less than or equal to 108 inches. The "length" of the package is considered to be the length of its longest side, and the "girth" of the package is the distance around the package perpendicular to its length. Fran wants to ship packages under the USPS large-package rates. Her package is a rectangular solid (see picture) whose length is 40 inches. What is the largest volume that her package can have?

The size of a TV screen is stated in inches, a 45-inch TV, a 60-inch TV, etc. But a TV screen or a cell phone screen is a surface so its size should be measured in square inches rather than inches. It turns out that the advertised screen size is actually the length of the diagonal line of the screen. So a cell phone with a 6-inch screen may have a different screen area than another cell phone that also has a 6-inch screen. Find the area of the rectangles. Round answer to two decimal places.
