Square–cube law
Summary
The square–cube law describes how an object's surface area and volume change when its size is scaled: if all linear dimensions are multiplied by a factor (k), its surface area increases by (k^2) while its volume (and, at constant density, its mass) increases by (k^3).
For example, doubling a cube's side length makes its surface area four times larger but its volume eight times larger. Consequently, as objects become larger, their surface-area-to-volume ratio decreases, creating important physical constraints: large animals have greater difficulty dissipating heat, large structures experience greater mechanical stresses, and engineering systems such as engines and cooling systems cannot simply be scaled up proportionally. The principle, first described by Galileo in 1638, is therefore fundamental to geometry, engineering, biology, biomechanics, and heat transfer.
