Best ResponseYou've already chosen the best response.0Hrm... This is a tough one, since drawing it out would be very beneficial as well. https://docs.google.com/drawings/edit?id=1crhrg5jI196FHJNvCH64xY02Ze_3EeObtkyAhBGV9zY&hl=en&authkey=CPGXwM4O Okay, so we can setup the equation now as such: (482x)+(362x)=V V=2x+2y Using both equations we should be able to solve for the max possible volume of the box.

Best ResponseYou've already chosen the best response.0Well we know that x is one length and y is another. Since we solved for y, we can substitute x=20, and solve for y. Does it make sense why?
