Directions Solve the given problem.
1 Biologists study characteristics of various living things. One way of comparing
different animals are to compare their sizes. For example, a mammal's surface area S
(in square centimeters) can be approximated by the model S = km⅔ where m is the
mass (in grams) of the mammal and k is a constant. The values of k for several
mammals are given in the table.
Mammal

Cow
