To find the sum of the interior angles of a polygon, you can use the formula:
\[ \text{Sum of interior angles} = (n - 2) \times 180^\circ \]
where \( n \) is the number of sides of the polygon.
For a polygon with 6 sides (a hexagon), you can substitute \( n = 6 \) into the formula:
\[ \text{Sum of interior angles} = (6 - 2) \times 180^\circ = 4 \times 180^\circ = 720^\circ \]
Thus, the sum of the interior angles of a hexagon is \( 720^\circ \).
