Find the value for k in the equation w kh3 for a baby who is 20 inches long and weighs 6 pounds?
Is it significantly fatter in proportin to its height than an adult?
With the limited information you give, we have to make some unsure assumptions.
w = weight in pounds
h = height in inches
w = k * h^3 (h cubed)
Dividing both sides by h^3, gives you
k = w/(h^3)
Insert you numerical values. However, you need to know the adult values to make a comparison.
I hope this helps. If not, repost your question in clearer terms and with adequate data. Thanks for asking.
