<image> When a faucet is not completely turned off, it will drip water. Now a container is placed under the loosely closed faucet, and the relationship between the amount of water in the container \(W(L)\) and the dripping time \(t(h)\) is shown in the figure. Use the graph to solve the following problems:
$$(1)$$ How many liters of water were originally in the container? 
$$(2)$$ Find the functional relationship between \(W\) and \(t\), and calculate the amount of water dripped in one month (30 days) under this dripping state.
