When the paper is folded in half, cut one villain, two halves and four halves three times at a time. When the paper is folded in half, the n- 1 power of 2 can be cut, that is, the product of n- 1 multiplied by 2.

According to the actual calculation, the size of the base paper of the new board is 840mm× 1 188mm (that is, the size of 16 sheets of A4 paper). If the paper thickness is 1mm, the size of the paper folded in half 1 time should be 840mm×593.5mm (including 0.5).

The actual size of the two folds is 593.5mm×4 19.5mm, and the size of the three folds is 295.75 mm× 419.5 mm. That is to say, the actual size after each fold is subtracted from the thickness loss of the folded edge (of course, if it is not folded in half but cut, this loss can be omitted). The paper size after four folds should be 2000.

Theoretically, the paper size should be 3.28 125mm×3.330625mm (not including the loss of hemming) at the 6th folding. However, if you calculate the loss by half, you can only fold it to the twelfth time.
