How to fold a small box with paper

Step 1: First, prepare a rectangular piece of paper, as shown in the figure below.

Step 2: Fold the paper in half along the center line, as shown in the figure below.

Step 3: After step 2, fold it in half again along the center line, as shown below.

Step 4: Fold the left half and the right half along the center line as shown in the figure below.

Step 5, then fold the two sides in half, as shown in the figure below.

Step 6: Fold to the right as shown by the arrow, and then fold the right side back to the left, as shown in the figure below.

Step 7: Fold the two corners on the left back and forth to align with the center line, and do the same operation on the right, as shown below.

Step 8: Similarly, fold the middle two corners in half along the left and right red lines, and operate the back two corners in the same way, as shown below.

Step 9: Then insert the small triangle folded for the second time into the big triangle folded for the first time, and finally open it in the direction of the arrow on the figure, as shown in the following figure.

Step 10: After opening, slightly adjust the carton to make it more stereoscopic, and the carton will be folded here, as shown below.

Data expansion: the paper box is a three-dimensional model, which consists of several polyhedrons with moving, stacking, folding and enclosing surfaces. The plane in the three-dimensional structure plays the role of dividing space in space. When faces in different parts are cut, rotated and folded, the resulting faces have different emotional expressions.
