When packaging an item according to Method 30, what width of barrier material is required for an item measuring 20 inches wide by 40 inches long by 10 inches high?

When packaging an item according to Method 30, the width of the barrier material is determined by calculating the total width needed to adequately cover and secure the dimensions of the item being packed.

For an item that measures 20 inches wide by 40 inches long by 10 inches high, the packaging method requires considering the largest dimension and the additional material needed to wrap around the item. Specifically, Method 30 typically involves using a barrier material that not only covers the item’s surface area but also allows for overlaps and securing at the corners.

In this scenario, the required width of the barrier material is calculated as follows:

• The item is 40 inches long and 20 inches wide. When calculating the total area to be covered for method packaging, the formula used generally is the width plus the height plus an allowance for overlap, plus an additional width for wrapping around. In this case, you would include both width dimensions and ensure that the lengths of the barrier cover adequately protect the item. The formula often used for Method 30 includes adding the height of the item (which stands at 10 inches) to ensure total coverage around the item.

Considering this calculation, you arrive at a total barrier width of 63 inches (20 inches width +
