What is the weight of a piece if the total gross weight of a mailing is 80 pounds and it consists of 200 pieces?

To find the weight of a single piece in a mailing with a total gross weight of 80 pounds and consisting of 200 pieces, you would divide the total weight by the number of pieces.

Mathematically, this is expressed as:

Weight of one piece = Total gross weight / Number of pieces

Weight of one piece = 80 pounds / 200 pieces

Performing the division:

Weight of one piece = 80 / 200 = 0.4 pounds

This means that each piece weighs 0.4 pounds. The precise calculation confirms that the answer is indeed 0.4000 pounds, making this the correct choice. This format is commonly used in bulk mailing scenarios to determine individual piece weight for cost analysis, processing, and shipping requirements.
