A mammal's surface area can be calculated by using the equation S(m) = km where s(m) is the surface area in square centimeters,
Virty [35]

Answer: 706 grams

Step-by-step explanation:

s(m) = km

So 6000 = 8.5m

Divide both sides by 8.5 to isolate m

6000/8.5 = 8.5m/8.5

705.88 = m

m = 706 (rounding up)
