From Wiktionary, the free dictionary
the square-cube law
- The mathematical principle that, as a shape grows in size, its volume grows faster than its surface area. Specifically, when an object undergoes a proportional increase in size, its new surface area is proportional to the square of the multiplier and its new volume is proportional to the cube of the multiplier.
The square-cube law helps to explain why large mammals like elephants have a harder time cooling themselves than smaller ones like mice.
