Different manufacturers pack differently. True 3/4 inch hardwood can be packed from about 38sq ft to about 60sq ft. Packaging can also depend on the width. Most all hardwood is also random lengths.
Look at the box sticker and it should say how many Sq ft it is per box. Divide that into 384
What if it was 8 planks to a box and they are about 7 or 8 in wide laminate
