It is not hard to draw there since I remember there is a cube figure template.

BTW, I have seen the combination questions you have lost before.
I feel sorry for that because you had made your effort in analyzing the question.

Take care.

Just Microsoft Word, Excel, PowerPoint, they have the clip art to draw common figures.

I joined some cubes together there~

What program do you use this is amazing!!!!
