Hi i post this here becasue i hope you can help me with a little question i have not yet been able to figure out myself. i know what the square cube law say: When an object undergoes a proportional increase in size, its new volume is proportional to the cube of the multiplier and its new surface area is proportional to the square of the multiplier. However all examples that i have found has been examples of very large examples like for example humans at 60 feet in height. That is not really helping me since i try to find out what the square cube law would say about something far smaller then that. But enough of a backstory I am writing a scfi/fantasy story for myself and the largest bipedal races are 6 meter or 19.685 foot or for simplicity 20 foot when they stand erect on two legs. Is this possible without breaking the square cube law? i estimate their weight under standard gravity at around 2000 - 2500 kilogram or 4409.25-5511.56 pounds Looking forward to your answers
