Hi Everyone! I'm working on a simulation game, but my mathematics skills are terrible, and I would like some help! The simulation I'm working on involves raising snakes. I know that a 20cm snake weighs 100grams, and that a 180cm snake weighs 4000grams. Could someone please give me an equation that will predict the length of my snake as it grows from 100grams to 4000grams? Thank you very much!

Assuming the snakes growth is linear, we can find an equation which models it. Using y=mx+b, Our equation is Now, plug in any x for length to find its weight in grams. For instance, if it is 30cm it weighs 343.75 grams

And any snake smaller than cm is made out of antimatter? I think the linear progress assumption was off.. You need to incorporate point . A second degree progression seems appropriate (even if you think in terms of actual snakes)! Then, this would be:

Yes, it could work. But, as I was thinking about this (and to be clear now  this is totally stupid to do anyhow), I think that the surface of a snake's body section across it's length axis does not grow with linear progression. I think it should be something much, much slower. Maybe logarithmic? So something like ?
