Let us the draw the front view pool.

$\"\"$

\

In the front view of pool width of the pool is not shown.

\

The volume of the pool can be find out by sum of rectangle part and triangle prism part.

\

The color blue indicates that the amount of water filled in the pool.

\

The volume of water already filled in pool is

$\"\"$

\

The length of the water filled can be find out by applying the property of similar triangles.

\

From the property of similar triangle the ratio of any two sides are equal.

\

$\"\"$

\

Therefore the length of the water filled is $\"\"$ .
