I'm planning to use Bora-care as a preventive measure on some exterior wood. But I don't understand how to calculate the amount of water and concentrate to use. Here is the label with instructions:

For this first project, I have 500 cu. inches of wood (about 5x100x1) and I'd like to use a 5:1 ratio. So how much concentrate should I mix with how much water for that volume of wood?
I know I can mix 5oz of water with 1oz of concentrate or 6oz total, but is that enough to treat 500 cu. inches of wood? What if I want to use the same 5:1 ratio for 1000 cu. in. of wood? or 10,000?

Your area calculation makes it seem like you are treating a single 8' long 1x6 board. Anyhoo, the amount you need depends on the porosity of the wood. The instructions say to apply "to the point of saturation". If your area calculations are correct, than you probably need less than 1 gal. of solution. So, at an approximate 5:1, you need about 105 oz. of water and 21 oz. of concentrate to make a tad bit less than a gal. of solution at 5:1.
P.S.- math is not my forte
P.S.S.- I don't think you need perfect accuracy here...
