All right, we're looking at a couple of 3d objects.
00:02
The first one is a cube, which is obviously three -dimensional square, so all sides are exactly the same length.
00:11
Drawing them can be a little bit tricky sometimes, but i think parallel lines, and that should help.
00:17
So here's a cube.
00:18
You can always draw in the three -dimensional part by finding that parallel line.
00:28
Not too bad.
00:28
Okay, there's our cube.
00:29
The second shape is a square pyramid.
00:32
So a square pyramid is, as it sounds, a pyramid that has a square base.
00:44
You can picture it like this.
00:49
I'm looking like this.
00:53
A very straight line.
00:54
There you go.
00:54
There's a square pyramid.
00:56
Then obviously this line that would come up to the top as well.
00:59
So there's our square pyramid.
01:00
We're looking at cross sections...
