A:
Roughly 0.0273192365 lbs per box.
Weight of cardboard = 100 pounds / cubic yard (46,656 cubic inches)
Weight of cardboard = 1 pound / 466.56 cubic inches
1 cubic inch = 0.00214334705 lbs
Thickness of box = 1.85 mils (0.0728346457 inches)
The box has five sides and four flaps; two flaps roughly equals the area of one side. Therefore, the box has a surface area of roughly 175 sq in.
SA * Thickness = Area
175 sq in * 0.0728346457 in = 12.7460629975 cubic in
0.00214334705 lbs * 12.7460629975 cubic in = 0.0273192365 lbs per box
