Interior Angles of a Regular Hexagon

Consider a regular hexagon, which is a polygon with six equal sides and angles. The measure of each interior angle of the hexagon can be calculated using the formula:

$$(n-2) \times 180$$

where $n$ is the number of sides in the polygon. For a hexagon, $n = 6$. Calculate the measure of each interior angle and determine the sum of all the interior angles of the regular hexagon.
