For the same item packaged under Method 30, what length of barrier material is necessary for dimensions of 20 inches wide by 40 inches long by 10 inches high?

To determine the correct length of barrier material necessary for an item packaged under Method 30, it's important to consider how the dimensions of the item align with the packaging requirements. Method 30 typically involves ensuring that there is adequate coverage of the item to provide protection.

In this case, the item has dimensions of 20 inches in width, 40 inches in length, and 10 inches in height. To find the length of the barrier material, you need to account for the surface area that needs to be covered, including enough material to wrap around and secure the item effectively.

The calculation generally involves considering the longest dimension of the item and adding extra length for overlap and the necessary wrapping to ensure all sides are secured. By assessing dimensions, the length should accommodate the length of the item and the height; typically, you'd add the width for proper folding and securing.

For a 20-inch width and a 10-inch height, if you consider both the length (40 inches) and the two heights (10 inches + 10 inches = 20 inches), you arrive at a total necessary length: 40 inches (length) + (2 x 10 inches for height) + some additional material for securing. This totals to about 60 inches
