Answer below.

Step-by-step explanation:

The magic constant of the magic square is 42. That means the sum of every column, every file and every diagonal must add up to 42.

The first column has 10 + 11 = 21. We need 42 - 21 = 21 to place in the middle square.

The second row now has 21 + 14 = 35. We add 42 - 35 = 7 in the rightmost square.

The last column now has 7 + 18 = 25. We need 42 - 25 = 17 in the upper square.

Note the diagonal is correct with 11 + 14 +  17 = 42

The first row has 10 + 17 = 27. We need 42 - 27 = 15 more

Finally, the second column has 14 + 15 = 29. To complete 42, we need 42 - 29 = 13

Note the last row has 11 + 13 + 18 = 42.

The magic square is complete. We have attached an image with the completed square.
