Esquisse two-Understanding form

This exercise is to understand form and geometry in the design process. We were given a 10mm x-board to construct a 5 side pyramid 100x100x100mm.

during this exercise we are challenged to work out the measurements of the side of the pyramid, accuracy of the angle in order to fold them properly into a pyramid.

Esquisse one-Understanding material

Exercise one -an introduction to the cardboard material, understand its structure and
learning the basic techniques to create 90 degree angle, 45 degree angle, curved corners and self locking system.

Below are images of my exploration to the cardboard itself.
This open ended cube 100x100x100mm will have a different folding technique in each corner.
