so far I have gotten 88-12x+12x^2=0 but I dont know what to do next!

anonymous · Answer

h=x
l=8-2

v=(8-2x)(11-2x)x
v=(8-2x)(11x-2x^2)
v=88x-6x^2+4x^3
v'=88-12x+12x^2  

Those are my previous steps to get there

:/

its okay, thanks for taking your time to look over it!

8 × 11 square inches

timo86m sorry I didnt understand that, is my work so far correct because I have done some of the problem as much as I could,just confused with what to do next

anonymous · Answer

I am not sure what you are going for. BUt A hint is that making a box with all sides the same size is the biggest box yo ucan make.

anonymous · Answer

yeah the problem is looking for the largest volume the box can make
