Answer:
If we write 6 in each of the boxes then sum of every row and columns will be 18
Explanation:
We can write 3 numbers in each row and 3 numbers in each column.
we know that
6+6+6=18
So, if we write 6 in each of the boxes then sum of every row and columns will be 18
i.e. the figure will be as follows:
6 6 6
6 6 6
6 6 6
The sum of every row and column is 18
