What is the sum of the interior angles of a hexagon?

Correct answer to question 42 (Mathematics Knowledge): 720 degrees

Method

For a polygon with n sides the interior angles sum to (n - 2) x 180. A hexagon has 6 sides, so the sum is 4 x 180 = 720 degrees. The choice 360 is the sum of the exterior angles, which is the same for every polygon.
