Okay, we have the volume of a rectangular prism is this, and so we need to find possible dimensions.
00:05
It's a fancy way to say, factor it out completely.
00:08
And you'll see we'll end up with three things multiplied.
00:11
First of all, c to the third, c to the squared, and c we can factor out a c, and four, fifty two and one, fifty two and one, fifty two and a hundred sixty can all be divided by four.
00:21
So if i divide four by four, i got one, c to the third, remove a c, we're only left with c squared.
00:27
52 divided by 4 is 13 and c squared if i take out a c i have one c left 160 divided by 4 is 40 and if i take the c out here there's no more c left now 4c hangs out in front but we have to think about a way to factor this and i recommend doing this we know we know we know that c squared the only way to get that is c times c and so that's our starting point now we just have to think of different factors of 40 that could get us to 13.

Everything's positive.
01:04
So this is going to be positive and that's going to be positive.
01:06
We know that's true...
