How it works
A regular slotted box (RSC) is cut from one flat blank. The blank is (2 × length + 2 × width + 3.5 cm glue flap) long and (height + width) wide, because the top and bottom flaps are each half the width.
Weight = blank area in m² × board grammage in g/m². Trimming waste is not included.
