Allen's rule is an ecogeographical rule formulated by Joel Asaph Allen in 1877,[1][2] broadly stating that animals adapted to cold climates have shorter limbs and bodily appendages than animals adapted to warm climates. More specifically, it states that the body surface area-to-volume ratio for homeothermic animals varies with the average temperature of the habitat to which they are adapted (i.e. the ratio is low in cold climates and high in hot climates).Animals living in cold climates have short ears, limbs and tails whereas animals found in hot climates have long ears,

Two rectangular prisms are each composed of eight unit cubes. A composite cube with a side of 2 has a volume of 8 units3 but a surface area of only 24 units2. A rectangular prism two cubes wide, one cube long and four cubes tall has the same volume, but a surface area of 28 units2.
