The table shows the activities and their durations and dependencies in a project.
\begin{array}{|c|c|c|}
\hline \text{Activity} & \text{Duration (Days)} & \text{Depends on} \\
\hline \text{A} & 8 & - \\
\hline \text{B} & 4 & \text{A} \\
\hline \text{C} & 4 & \text{B} \\
\hline \text{D} & 4 & \text{C}, \text{L} \\
\hline \text{F} & 4 & \text{A} \\
\hline \text{G} & 4 & \text{F} \\
\hline \text{H} & 6 & \text{G, L} \\
\hline \text{K} & 10 & \text{A} \\
\hline \text{L} & 6 & \text{F, K} \\
\hline
\end{array}
The total duration (in days) of the project is $\_\_\_\_\_\_\_$ (in integer).
