I think it's basic I'm studying it at high school and I'm led to believe that this shouldn't be that difficult!
The question reads: A rectangular box is to be made to the following requirements:
1) The length must be one and a half times the width. 2) The twelve edges must have a total length of 6m.
Find the dimensions of the box that meets these requirements and that maximize the volume.
I have the answer at the back of the book if that'd help out anyone? Thanks for your help I really appreciate it.
My (failed) attempts so far: (Math's isnt my forte)
1.5(4w) + 4w +4h = 6m
then got it down to 1w = (6-4h)/10
Subbed it into the formula I made: 1.5((6-4h)/10) + 4((6-4h)/10) +4h = 6 but it ended up saying x=x on my calc. I am lost!
