A mammal's surface area can be calculated by using the equation S = km^2/3 where S is the surface area in square centimeters, k is the constant and m is the mass in grams of the animal. What is the surface area of a mammal with k = 9.75 and m = 3.4 x 10^3. Round your answer to the nearest whole number (do not leave your answer in scientific notation).
