Default proportional math problem

Hey, I'm practicing for my math exam tmw.

Can someone help me with this issue:

"A frog's weight is proportional to it's length, raised to the 3rd power. "Could the formula be as simple as: W = L^3

?

Thanks in advance!

You left out the constant of proportionality.

W = kL^3
