 So let's try this problem. It's a little trickier than most of those conversions that we've been doing. It says convert 1.8 inches squared to centimeter squared, okay? So you'll notice that inches squared, that's an area, right? It's a length times a length, so that's an area. But anyway, so that area, let's just say 1.8 inches squared. And you'll always get this conversion factor here, 1 inch equals 2.54 centimeters. It's a good one to kind of keep in your head. And it wants it in centimeter squared, which is also an area, of course, right? So the thing you want to make sure you do is remember that this isn't just inches, it's inches squared, okay? So when you convert, you're going to have to take that, or cancel that inches out twice, okay? So in order to do that, so we have this conversion factor, 1 inch, 2.54 centimeters. So when we do that, that doesn't cancel out both of them. It just cancels out one of them, right? So we're going to have to do it again. And so when we multiply this times this, we get centimeter squared as our unit. So again, a lot of times when I do these ones, people think, oh, it's so obvious, but when they go home and do it by themselves before they try to get here. I got 11.6, so we're going to be 12 centimeters squared. So I multiply it 1.8 times 2.54 times 2.5. And that gets you, in this case, the calculator gave me 11.6, and now it's going to round up. But the units, of course, are centimeters times centimeters, giving you centimeters squared. Are there any other questions? Just square the conversion out, right? Yeah, you could take this conversion and square the whole thing. Yeah, so I mean, another way to do this, short hand. Questions on that one? Questions, questions?
