$60$

#### Work Step by Step

Recall the acronym PEDMAS, which tells us the order of operations:
P: Parenthesis and other grouping symbols (We do everything in parenthesis first).
E: Exponents
D/M: Division and Multiplication (from left to right)
A/S: Addition and Subtraction (from left to right)
Evaluate by substituting the given value of the variable and then using order of operations to simplify:
$=6+2(11-8)^3
\\=6+2(3^3)
\\=6+2(27)
\\=6+54
\\=60$
