To find the weight of the box and the packaging material, we can subtract the weight of the refrigerator from the total weight.
Total weight (refrigerator + box + packaging) = 205 pounds
Weight of the refrigerator = 192 pounds
Weight of the box and packaging material = Total weight - Weight of the refrigerator
Weight of the box and packaging material = 205 pounds - 192 pounds
Weight of the box and packaging material = 13 pounds
Therefore, the weight of the box and the packaging material is 13 pounds.
