Pythagorus Theorum and a Gift Cube!

I cannot lie, because my first attempt was rather "gung-ho".  The intent was to make 4 triangles and stick them on a wrap and roll them up like you would a jewellery roll to make a cube. However, when I put the four triangles together, the angles were way off course!

Luckily I have an In-House Consultant who is a retired Civil Engineer (aka hubby) who reminded me of Pythagorus' Theorum and I had to get those little grey cells working to calculate the precise measurements rather than leave it to chance.

This was one of the special projects I designed for my club ladies this month which they found daunting at first, but once having done the first box, the rest was easy.



Don't believe me?  Roll VT!  I made the mistakes so you don't have to!
