To factorize the expression $27x^3 - 64$, recognize that this is a difference of cubes since $27x^3 = (3x)^3$ and $64 = 4^3$. The general formula for factoring a difference of cubes is:

$a^3 - b^3 = (a - b)(a^2 + ab + b^2)$

Here, $a = 3x$ and $b = 4$. Applying the formula:

$27x^3 - 64 = (3x - 4)((3x)^2 + (3x)(4) + 4^2)$

Now, simplify each term:

$= (3x - 4)(9x^2 + 12x + 16)$

Thus, the factorization of $27x^3 - 64$ is:

$(3x - 4)(9x^2 + 12x + 16)$
