6. Let's call "sawing" the following operation on a polygon:

a) Divide each side of the polygon into three equal parts.

b) Choose the middle part as the base of an equilateral triangle located outside the polygon.

c) Remove the base and add the other two sides.

Let $M_{0}$ be an equilateral triangle, $M_{1}$ be the polygon obtained by sawing $M_{0}$, $M_{2}$ be obtained by sawing $M_{1}$, ..., $M_{2018}$ be obtained by sawing $M_{2017}$.

In the figure, $M_{0}, M_{1}$, and $M_{2}$ are shown.

Find $S\left(M_{2018}\right)$ if it is known that $S\left(M_{0}\right)=3$. Provide the value of $S\left(M_{2018}\right)$ rounded to the hundredths.
