Our Challenge was to make a open box from a 20 cm by 20 cm piece of paper by cutting our four squares in the corners and folding the flaps. We had to make a box hold the biggest volume of box you can make. I made a box with 3 cm by 3 cm square corner flaps for a practice and then a 1 cm square flaps. Here they are.
|This can hold 8x9=72 cubes|
|This one can hold 6x7=42 cubes|
