Fireplace wood is rapidly becoming one of the most expensive fuels for the household and one which the homeowner least understands how to buy by measurement. Do not buy firewood by the "Pickup Load" or by the "Rick", which are not legal standards. Ask for the exact dimensions of the wood when it is stacked at your home, and buy accordingly. A legal cord of wood is 4 feet high, 4 feet wide and 8 feet long or 128 cubic feet. Number of board feet in a log = 1/4(d-4) L, where "d" = diameter of log (taken inside the bark at the small end) in inches, and L = length of log in feet. The 4 inches subtracted are an allowance for slab. Remember to square the formula before multiplying by the length.
