No it's not a stupid as it sounds. How many feet of say 12-16in dia logs would yield one cord. If you had to guess.

That would work out to 192ft.1 cord = 128 Cubic Feet.
But If I were to guesstimate on how many 12" to 16" diameter rounds cut to 16" lengths were needed to fill a volume of 128 Cu.Ft. ....my guess would be about 144 rounds.
4’x4’x8’ is a full cord. 4’xcut length x 8’ is called a face cord. Plug in your length and do the mathThat would work out to 192ft.
So here are the figures that I used to make my "Guesstimate" based on the dimensions of the box on my trailer that is = to 132 Cu.Ft. (Volume = L x W x H) Trailer Box is 12' x 6' x 22". Because one of the dimensions is inches I convert all dimensions to inches.That would work out to 192ft.
Diameter is the key here4’x4’x8’ is a full cord. 4’xcut length x 8’ is called a face cord. Plug in your length and do the math
It’s all measure of volume. A full cord is 128 cubic feet (4 x 8 x 4).Diameter is the key here
So all that rocket science gets you pretty close to my "guess of 128' if using 12" rounds?It’s all measure of volume. A full cord is 128 cubic feet (4 x 8 x 4).
Since we’re dealing with inches (diameter), we first convert cord cubic feet to inches (48 x 96 x 48) = 221,184
Can also simply multiply total cubic feet by 12^3 to convert to inches:
128 x 1,728 = 221,184
Second, using the average diameter of log size suggested by the op (14”), we find the area of a circle (cross-sectional area of the log) using area formula:
π * r2
We do this by multiplying π (3.14) by the radius squared:
7 x 7 = 49
3.14 x 49 = 153.86
Last, to determine the total linear length of the log, we divide the cubic inches in a cord by the area of the circle in the last step, then convert inches back to feet:
221,184 / 153.86
= 1,437.56”
Convert back to feet:
1,437.56” / 12
= 119.79 feet
Total linear feet of 14” diameter log equal to a full cord is: 119.79’
No void space for all those 14" rounds?It’s all measure of volume. A full cord is 128 cubic feet (4 x 8 x 4).

I prefer Motel "6". They leave the light on for ya. lmao OTSo all that rocket science gets you pretty close to my "guess of 128' if using 12" rounds?
I may not be a scientist, but I did stay at a holiday inn one time. I've also put a cord of wood in my trailers once or twice .

Only once or twice? Ha. I know you’ve been around long enough that it’s probably more like once or twice every other daySo all that rocket science gets you pretty close to my "guess of 128' if using 12" rounds?

Voids created by rounds aren’t a factor here.No void space for all those 14" rounds?
I agree with using 10% as a typical air space factor. That has been what myself and others often came up with over the years.A 16" round , 12" long is 1.5 cubic ft.... If it is 16" long you need to multiply 1.33 to the 1.5 cu ft.. SO, 12.5 X1.33 is 1.995 cu. ft. We will go with 1.75 cu ft. cause the bark will fall off. You will need 73 logs 16" long and 16" in diameter to make a cord. 128 cu. ft in a cord . 128 divided by 1.75 comes to 73. . That would be a perfectly tight fit however. I am sure with the air space you can knock off 10% and that would be 66 logs. That seems about right. If I am wrong, let me know, I would like to know myself.
one 16 ft log, Let's say... 12 inches at the big end... about 10 inches in the middle??In my experience, ten 16' logs averaging a foot in diameter will turn into a stacked cord more or less. No tape measure required, but I do need to take my mitts off.
Or - if you have a tree service friend - ONE 16' log ~3' in diameter will do it too.
