We're told that a box is completely filled with 18 cubic units or unit cubes, okay, which would measure one by one going across and up and down.
00:17
And we're asked, what is the actual volume of that? well, that's a basic understanding of what volume actually means.
00:24
So let's just imagine here that i have this 2 by 3 by 3 box.
00:29
And let's talk about what that means.
00:31
That means that if it's two inches or two feet, it means that i could cut it in half and have two exactly the same parts on either side.
00:40
So i'd have the same number top and bottom.
00:42
And then measuring by three, so i could cut it this way, and it would be exactly thirds.
00:49
All right.
00:49
And then again, the two would follow across back this way.
00:53
All right.
00:54
And hopefully you can kind of see my three -dimensional drawing here.
00:58
It's going back into the thirds that way.
01:01
And last but not least, going up the sides, we would also, since it was three deep, we would cut it up and down that way, and they would go across the top...
