I think drawing a picture could be very useful for students.
00:05
If you notice, it does say it's a square piece of cardboard or box.
00:11
I guess it does really matter.
00:13
But you have four inches cut from each corner.
00:18
And so as you fold that up, i'm going to try and make this look kind of like a box.
00:23
Not very good at drawing, but stick with me here.
00:28
Oh, that is a terrible box.
00:29
But anyway, where the heights of these are four, now be careful because this is no longer an x by x by x.
00:38
It would be x minus eight, because you have to remove four on each side.
00:43
Now this would also be an x minus eight.
00:46
So if you create an equation of x minus eight times x minus eight times four, because remember volume equals length, times width times height that's going to give you your volume of uh what do we have 3 ,844 cubic inches.
01:09
Now what i would probably do is divide the four over as the same time that i try to foil that out that i would have x squared minus 16x plus 64.

You don't have to do it my way but my way does work...
