I like the problem and the setup of the problem.
00:03
I don't know if you actually need the volume.
00:07
I could talk about that, but i don't know if that's the endgame.
00:10
But we have these 22 by 22 inches, and then you're removing x by x on each side.
00:20
And i'm just trying to point out a few x's because if i redraw that picture, not only are you removing an x from each side, but you're removing a second x.
00:31
So it's 22 minus 2x.
00:33
Do the same thing over here.
00:37
Trying to draw it so you can kind of see the visual.
00:40
22 minus 2x, but then i also have a height of x.
00:44
So i don't know if you need the volume equation, but i would just write it as length times width times height, but my length and the width are the same.
00:52
So i just might write it as 22 minus 2x, the quantity being squared, and then times the height of x.
00:59
So not sure if you need that equation.
01:01
But what did they talk about for the domain is it only makes sense for your x values.
01:08
I can see that they write in interval notation values for x that satisfy that x can only be between 0 and 11.
01:18
So sometimes i just like to write that answer out first...
