Preservation and Packing (PACK-1A) Practice Test

Determining how many straps a large heavy fiberboard box needs depends on the box’s shape, not its weight or volume alone. To figure the strap count you must know all three dimensions: length, height, and width. The height and width define the cross-section of the box, which lets you calculate the girth or perimeter around the box where straps will wrap. The length tells you how the straps run along the long axis and how many segments or passes are needed along that direction. If you only know volume or weight, you could have boxes with very different shapes requiring different strap configurations, so those measures don’t reliably tell you how many straps are needed. Knowing all three dimensions allows you to determine the correct number and placement of straps to secure the box properly.
