Question 787320: Majorie Jensen has a sheet of tin 12 cm by 16 cm. She plans to make a box by
cutting the squares out of each of the four corners and folding up the remaining edges. How
large a square should she cut so that the finished box will have a length that is three
times the width?
I tried to do the equation but it did not make sense when I tried it. This is what I got:
let x= how large square should be
12*16-4x= 3*12
Please help!

One more time...from the very top.

Let be the measure of a side of one of the cut out squares.

Then the length of the bottom will be because there is a square cut out on each end. Likewise the width of the bottom after the folding is done will be

So if you want the length of the bottom to be three times the width:



Solve for which is the side dimension of the squares and sufficient to uniquely identify the size of the squares.
