Fat Cow Enigma

Story: A steer weighing 630 kilograms requires 13,500 calories a day to maintain its weight. That amount of food turns out to be proportional to its external surface.

Enigma: How many calories does a steer of 420 kilograms require?

Solution: Weight is proportional to linear dimension (length or girth of the steer) cubed. Surface area is proportional to linear dimension squared. Therefore, 13,500 x [ ( 420/630)1/3 ] 2 = 10,300 calories.
