(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

The object is to fold and then cut square corners from a standard 8.5 by 11 inch sheet of paper to create a suitcase of maximal volume

2. Relevant equations

V=L*W*H

SA=2LW+2LH+2WH

3. The attempt at a solution

93.5=2(8.5-2x)(11-2x)+2(11-2x)2x+2(2x)(8.5-2x)

x=1.375

then i plugg it into the Volume equation my lenghts are

(8.5-2(1.375))=5.75

(11-2(1.375))=8.25

1.375=1.375

Then i try to build it out of a piece of paper and it doesnâ€™t close like it is suppose too, can anyone figure out where I went wrong it would be greatly appreciated
