Thread: Rectangular Package

A Rectangular package sent by a delivery can have a maximum combined length and girth (perimeter of a cross section) of 120 inches.

Here, there is a picture, which is a 3D package, with length of y, and with of x.

The problem is the following: Give a formula for the volume of the package.


Thank you very much

Thank you very much

1. I've made a sketch of the package (see attachment)

2. Since there are only given 2 measures I assume that the package should have a square cross-section.

3. The volume of the package is calculated by:



with the constraints



4. Therefore the volume is a function of the width of the package:

We can't see any picture.

With what you gave us, all I can tell you is that volume calculation
of a rectangular package also requires height.
