Hi, all right, so polyhagen 1, which is made up of 540 identical cubes, is similar to polyhedron 2, which is made up of 20 cubes of the same size.
00:11
What is the scale factor? i didn't mean a cross -iron.
00:14
Scale factor of polyhedron 1 to 2.
00:18
Okay? all right, so let's do that first.
00:22
So what it means by 1 to 2 is that the 1 is the 540 and that's 20.
00:33
Okay, now this is the ratio of the volume of one to the volume of two so this is not going to be our scale factor scale factor is represented by lowercase k.
00:43
This isn't going to be our scale factor this is actually a scale factor cube because this is about volume regular o k is going to be the cube root of this because scale factor is a one -dimensional thing and we're talking volume and cubes and stuff is a three -dimensional thing all right, let's just divide this so this is 540 divided by 20 that's 27 so that is k cubed is 27.

That means our scale factor is going to be the cube root of 27, which is three...
