When x is 7 I added 10 to get the height. Then to get the girth I multiple 2 by width plus 2 by height. After I found the girth, I moved on to the length which I subtract the total – girth. Then I found the volume by multiplying length by height by weigh. Y= (165-(4x + 20) – (x+10) – x. 2. We found the maximum point then we graph x= height and the y= volume. 3. I don’t get what you are asking me in question number.

When x is x you need to add 10 to get the width The height stady the same as the x. Then to find the girth you need to multiple 2((x+10) + x) = Girth. To find the length you use either 130 or 165 i am going to us 130 so then 130 meaning the total i'll subtract it from 2((x+10)+ x) which
i sublifia it to 4x+20. Then i'll will find the volume by doing (total - (4x+ 20) by(x+10) by (x) and that should give you your volume.

When we graph we use the x for the height and the y for the volume. The way we organizes the date was by names FedEx and UPS. Then in the graph we organized it by color and fuction.
