Let's look at the world all around us and see that, in fact, we are in three-dimensional space. There are three different directions we can move. We can move front and back, up and down, and side-to-side. When you put all those dimensions together, we can build really neat three-dimensional objects. Now we have seen a lot of these things, they are sort of familiar, like the cube for example, which as you can see has faces and edges and vertices, the sharp corner points. We can actually count these things.
We've jumped to the Volume and Surface Area subchapter in our 6th grade math videos. Today's free video covers three-dimensional figures. Edward Burger explains counting faces, edges, and vertices and the different types of three-dimensional figures you'll encounter. This video contains two different lectures, so make certain you click the forward button directly to the left of the time stamp to move to the next lecture. Keep following us as we post the entire subchapter on Volume and Surface Area this week. Then test your skills on Friday's subchapter worksheet covering this week's video lectures.
