2. Folded Paper Cube

February 15, 2016

You can find a number of ways to fold an origami cube on the web. Jeremey Shafer will show you how to fold a seamless cube (below) here.

It’s a bit tricky. Wikihow has very clear instructions on how to fold a simple paper cube here.

But, Mathspig prefers the paper cube designed by Phillip Stromberg of the Netherlands.His cube calendar (below) comes inside one of these paper cubes. This was a very spooky calendar as Mathspig could see her life disappearing in front of her eyes for one whole year. ARrrrgh!

Here is the way to fold a Phillip Stromberg cube:

Mathspig Cube 2.1

Step 1: Draw up a grid on cardboard 7 x 6 square.

Mathspig used 8 cm squares on paper. Cardboard would make a stronger cube.

Mathspig Cube 2.2

Step 2: Count of squares and draw this pattern.

Mathspig Cube 2.3

Step 3: Cut out the cube template.

Step 4: Use scissors to score all folding edges.

Step 5: Score the perpendicular bisectors of the isoceles triangles. Ha Ha! I’ve always wanted to say that!!!!

Mathspig Cube 2.6

Step 6: Fold the cube sides up, tucking the extended flaps over the triangles.

Step 6: Fold down the cube lid!!!

OK! It may take some practice. But mathspig likes her cube.

Notice the Diagonals!!!!

This is a properly engineered Spaghetti Cube.

Why stop at a cube? You’re on a roll now.

Try a spaghetti and marshmallow tower.

Fabulous instructions here.
