Hexagons & Triangles, easy way to calculate size?
So I took a class last weekend and learned how to make this:

These are obviously only partially sewn together at this point; I have more blues I'm going to mix in so this was just the start I got during class where I only had 3 colors with me.
I'm trying to figure out if there's an easy way to figure out how many hexagons and how many triangles I need to make a king size quilt.
Each hexagon is 6" finished, measuring flat side to flat side. (Top to bottom, in the picture above). So I end up with rows that finish at 6", so height is easy.
Width, though...these aren't going to be 6" from point to point; it's going to be more. Can anybody tell me what that formula is?
I know I could just measure these and find out, but I want to know the math, so next time when I'm designing something like this I can figure it out before cutting & sewing anything together.
And then the triangles...I THINK I need 2 triangles per hexagon..? Does that look about right?
I think I can just sort of ignore the triangles in the measurements, since those just sort of fill in between the hexagons. Alternating rows end with half-hexagons on both sides, so it's always the same number of hexagons per row even though they're offset. But I still need to figure out how many triangles to cut.
I have a bunch of fabric cut, but I haven't counted anything yet.
