why is it impossible for animals to grow to certain sizes without collapsing under their own weight? If you just scale everything up 1:1, why can’t they just function normally at increased sizes?
In: Biology
When measurements double (x2), then area goes up by a factor of 4, (2×2 ), and volume goes up by a factor of 8 (2x2x2)
cube 1x1x1
SA = 1+1+1+1+1+1=6 square units or 1×6
Vol = 1x1x1=1 cubed units
Cube 2x2x2
SA = 2×2=4, so 4×6=24 square units
Vol = 2x2x2=8 cubed units
So doubling the length will produce 8 times the volume (not double), a twice tall person will be 12ft, but weigh 1600lbs, and bones can’t support it.
