change shape but maintaining the same volume

volume = length * width * height

so u could use e.g.:

height =  volume / (length * width) to find the corresponding hight to a given v, l & w

but best of course would be to use galapagos, in your case its a quite simple definition..

I don't think galapagos is necessary for this. One approach that doesn't let you specify specific dimensions but gives you control over the proportion would be to simply let the box's volume change, but then scale it by a factor of the cube root of the desired volume over the actual volume.

Yeah, Andrew that is cool!

I love when it comes to math, even if I am not good at it :-)

thanks for adding

so for area (2d) boxs would we scale by square root of desired area?

answered my own question, it works for area :)
