Problem Analysis

We are given that 8 identical boxes with nails were sent to two construction sites. When a total of 60 kg of nails were used on both sites, one site had 3 full boxes remaining, while the other had 2 full boxes remaining. We need to determine the number of nails in each box.

Solution

Let's assume that each box contains x kg of nails.

From the given information, we can form the following equations:

Equation 1: 8x = 60 (total nails used on both sites is 60 kg) Equation 2: (8 - 3)x = (8 - 2)x + 60 (nails remaining on one site is 3 full boxes, while on the other site it is 2 full boxes)

Simplifying Equation 2: 5x = 2x + 60 5x - 2x = 60 3x = 60 x = 60 / 3 x = 20

Therefore, each box contains 20 kg of nails.

Answer

Each box contains 20 kg of nails.
