Answer 2

Calculation of the Weight of Nails in Each Box

To determine the weight of nails in each box, we can use the information provided. We know that 10 identical boxes were sent to the construction sites, and a total of 69 kg of nails were used. On the first construction site, 5 full boxes remained, and on the second construction site, 2 boxes remained.

Let's calculate the weight of nails in each box:

1. Calculate the total weight of the nails used: - Total weight of nails used = 69 kg.

2. Calculate the weight of the remaining boxes: - Weight of nails in the remaining boxes on the first construction site = 5 boxes - Weight of nails in the remaining boxes on the second construction site = 2 boxes

3. Calculate the weight of nails in each box: - Weight of nails in each box = (Total weight of nails used - Weight of nails in the remaining boxes) / Number of boxes sent

Let's plug in the values and calculate:

Weight of nails in each box = (69 kg - (5 boxes + 2 boxes)) / 10 boxes

Weight of nails in each box = 62 kg / 10 boxes

Weight of nails in each box = 6.2 kg

Therefore, each box contains 6.2 kg of nails.
