Okay, so it gives you two different scenarios for rectangle, for square pyramids.
00:07
And it says they have the same volume.
00:10
So we're going to use the volume formula for this for pyramids.
00:14
So one -third area of the base times the height, which our base here is a square.
00:20
So the area of a square is s -squared.
00:25
So since they're equal, i can find the volume of the first, one -third, oh, that's my three, that's a two.
00:32
I'm going to raise that and try it a little bit better.
00:35
One third times 20 squared because that was the length of the base of one side of the base.
00:43
And then 21 was the height...
