Consider cubes with different side lengths below:
Cube with length(cm)(1)(2)(3)
Surface area(cm2)(6)(24)(54)
Volume(cm3)(1)(8)(27)
Surface area to volume ratio(6)(3)(2)
From the above, we can see that the smaller the volume, the larger is the surface area to volume ratio. In animals, the metabolic rate depends on the body's surface
area. 體積較細既動物 has a smaller body size(i.e. volume) and therefore a larger
surface area to volume ratio. They have higher metabolic rate.
