So a stack of 16 firewood can only be 16 wide or a multiple of 16.
Dimensions of a cord of split wood.
Using full feet for the width can be a problem since standard length for pieces of firewood is usually 16 inches.
Its total volume should be 128 cubic feet 3 5 cubic meters.
Or any other arrangement of linear measurements that yields the same volume.
This corresponds to a well stacked woodpile 4 feet 122 cm high 8 feet 244 cm wide and 4 feet 122 cm deep.
A full cord also referred to as a cord is a stack of wood that measures 4 feet 1 2 m wide 4 feet 1 2 m tall and 8 feet 2 4 m long.
The common dimension to get a cord of wood is 4 x4 x8 but there are many dimensions that will add up to 128 cubic feet.
A cord of firewood has a total volume of 128 cubic feet which is actually a lot of firewood.
Examples are 2x4x16 and 1x4x32.
