V=volume; N=number of sides=number of triangles that forms base of hexagon;

A=area of each triangle(quanity in parenthesis); h=height of hexagon.

The 6 triangles formed by drawing a line from the center to each vertex are equalateral. Therefore, the height of each triangle is 14sin60=12.1. I hope this explanation is sufficient.
