$(4g-3h)(16g^2+12gh+9h^2)$
$\bf{\text{Solution Outline:}}$ To factor the given expression, $64g^3-27h^3 ,$ use the factoring of the sum/difference of $2$ cubes. $\bf{\text{Solution Details:}}$ Using $a^3+b^3=(a+b)(a^2-ab+b^2)$ or $a^3-b^3=(a-b)(a^2+ab+b^2)$ or the factoring of the sum/difference of $2$ cubes, the expression above is equivalent to \begin{array}{l}\require{cancel} (4g-3h)[(4g)^2+4g(3h)+(3h)^2] \\\\= (4g-3h)(16g^2+12gh+9h^2) .\end{array}
