# Growth of wood

The annual growth of wood in the forest is estimated at 2%. In how many years will make the forest volume double?

Result

n =  35

#### Solution:

$q=2 \%=1 + \dfrac{ 2 }{ 100 }=1.02 \ \\ \ \\ q^n=2 \ \\ n \ln q=\ln 2 \ \\ \ \\ n=\ln(2) / \ln(q)=\ln(2) / \ln(1.02) \doteq 35.0028 \doteq 35$
