Dear Julia and Liam,

1. Liam's drawing for the first line in the second row is correct. I've changed the answer.

2. Liam is also correct that the other cube in that row needs another line. I put it in there, but it's almost impossible to see.

3. I can't figure out how to use the Pythagorean theorem either, so I took that comment out.

4. I'm glad Liam figured out the meaning of drawing the cubes in the dodecahedron. I do agree with you and changed the wording in the Lesson.

Thanks so very much. Your comments were very helpful. The corrections will be on the Corrections page soon.
