The given expression is:

\[
\lim_{{x \to 3}} \frac{x^3 - 27}{x - 3}
\]

Let's break it down:

1. First, notice that \(x^3 - 27\) is a difference of cubes, which can be factored as:

\[
x^3 - 27 = (x - 3)(x^2 + 3x + 9)
\]

2. Now substitute this into the original limit expression:

\[
\lim_{{x \to 3}} \frac{(x - 3)(x^2 + 3x + 9)}{x - 3}
\]

3. The \(x - 3\) terms cancel out:

\[
\lim_{{x \to 3}} (x^2 + 3x + 9)
\]

4. Now, substitute \(x = 3\) into the simplified expression:

\[
3^2 + 3(3) + 9 = 9 + 9 + 9 = 27
\]

Thus, the value of the limit is:

\[
\boxed{27}
\]
