A particular parcel sercive will accept only packages with length no more than 128 inches and length plus girth(xz)(width times height) no more than 145 inches.

What are the dimensions of the largest volume package the parcel service will accept?

This is the problem, but I just need to figure/know the objective equation and subject equation.

Do i use 2zx+2xy+2yz as my objective function and for my subject function would it be something like zx-17=0?

NOTICE: THIS IS A RECTANGULAR BOX

2. Relevant equations

Using Lagrange Multipliers

A=xy+xz+yz

3. The attempt at a solution

considering that i know that the area function is 2zx+2xy+2yz

Do i use 2zx+2xy+2yz as my objective function and for my subject function would it be something like zx-17=0?
