After wrapping, how large must the barrier be for goggles measuring 10 inches long by 3 inches high by 8 inches wide according to Method 41?

The correct choice specifies a barrier size of 25 inches long by 29 inches wide, which is suitable for effective wrapping and protection of the goggles, ensuring they are adequately shielded from damage during storage and transport.

In Method 41, it's important that the barrier dimensions are larger than the items being wrapped to allow for proper padding and coverage. The dimensions of the goggles—10 inches long, 3 inches high, and 8 inches wide—require a careful calculation to determine the necessary barrier size.

To accommodate these dimensions with sufficient excess for wrapping, a barrier that adds an appropriate margin around each side is essential. The selected dimensions in option C provide adequate length and width to allow for these necessary excesses. This ensures that the goggles are not only protected but also allows for the inclusion of cushioning materials if needed.

While the other options present various dimensions, they either do not fit the guideline as closely or offer size configurations that might not enhance protection or ease of handling for this specific item.
