The Impossible Pyramid Puzzle
Author: Gianni A. Sarcone

Topological puzzle - difficulty level bulbbulbbulb
Can you reproduce this pyramid-like figure just by cutting and folding a single piece of rectangular strong paper? (you cannot cut the paper into two or more different pieces)

• Reproduisez la figure ci-dessous en découpant et en pliant une feuille de papier A5. Il ne doit point rester de chutes de papier, et la structure tridimensionnelle doit former un tout unique.

• Ricavate questa struttura tridimensionale ritagliando e ripiegando un unico foglio di carta A5 senza l’utilizzo di nastro adesivo (il foglio non può essere tagliato in parti distinte!).
