To know the life span of the wolf and the lion, we simply substitute their mass to the formula for L.
Mass of wolf:
[tex]L=12 m^{ \frac{1}{5} }= 12 (32)^{ \frac{1}{5} }=24[/tex]
Mass of lion:
[tex]L=12 m^{ \frac{1}{5} }= 12 (243)^{ \frac{1}{5} }=36[/tex]
Therefore, the wolf has a life span of 24 and the lion has a life span of 36. With this information, we can determine how much longer the life span of the lion is:
[tex]36-24=12[/tex]
ANSWER: The life span of the lion is 12 longer than the life span of the wolf.
