Divide 2liter volume
This was one of the most difficult things we had to make, with a ton of conditions
we had to take a volume of 2 liters and divide it into at least 6 parts ,where the parts are of the same shape family and their volumes are proportional one to another. and the parts have to be put together so they stay together without glueing, and the final thing has to look like something, a total shape. well nobody really understood what we had to do.
these are always the same parts , just put together differently. the blue one is out of paper. the rest is plastic
I figured out a better one, very similar to this but it was too late to make it
