1. There were 2013 empty boxes. In one of them, 13 new boxes (not nested inside each other) were placed. Thus, there became 2026 boxes. In one of them, 13 new boxes (not nested inside each other) were placed again, and so on. After several such operations, there became 2013 non-empty boxes. How many boxes are there in total? Answer: 28182.
# Solution.

After each operation, the number of non-empty boxes increases by 1. Initially, there were no non-empty boxes. Therefore, a total of 2013 operations were performed. With each operation, 13 new boxes are added. Thus, we have

$2013 + 13 \times 2013 = 2013 \times 14 = 28182$.
