The surface area S (in square centimeters) of a large dog
can be approximated by the model S = 11.2m^2/3 where m is the mass (in grams) of the dog. A Labrador retriever’s mass is about three times the mass of a Scottish terrier. Is its surface area also three times that of a Scottish terrier?
Algebra 2 -
Ratio = 11.2(3m)^(2/3) / 11.2m*(2/3) = 11.2*2.08m^(2/3) / 11.2*m^(2/3) = 2.08
Labrador S. = 2.08 times Sottish terrier S.
