Answer:

      4       14       12

     18       10       2

      8        6       16

Step-by-step explanation:

It is very easy task.You already have the grid with magic number 15 which is following

      2       7       6

      9       5       1

      4       3       8

Now just multiply all the rows with 2 to get the desire magic box with magic number 30

      4       14       12

     18       10       2

      8        6       16

Now you can see that

from every side sum is equal to 30

For example

4 + 14 + 12 = 30          From left to right

4 + 18 + 8 = 30            From up to down

4 + 10 + 16 = 30           In the Main diagonal

You can check for all other sides

Thus

      4       14       12

     18       10       2

      8        6       16

It is the desire magic box the magic number 30

Answer:

4       14       12

18       10       2

8        6       16

Step-by-step explanation:

Given:- Magic grid with number 15 which is

                                     2         7         6

                                     9         5         1

                                     4         3         8

To Find:- A grid with magic number 30 such that sum of the rows, sum of the columns and sum of the diagonal elements is 30.

Solution:-

Grid with magic number 15 is given.

To obtain the grid with magic number 30, all we need to do is multiply the grid of 15 with 2.

               2         7         6                                        4        14         12

               9         5         1        ×       2      =             18       10          2

               4         3         8                                         8        6          16

To evaluate our result, let's check if sum of rows, sum of columns and sum of diagonals = 30.

ROW 1 :-  4 + 14 + 12 = 30

ROW 2 :- 18 + 10 + 2 = 30

ROW 3 :- 8 + 6 + 16 = 30

COLUMN 1 :- 4 + 18 + 8 = 30

COLUMN 2 :- 14 + 10 + 6 = 30

COLUMN 3 :- 12 + 2 + 16 = 30

DIAGONAL 1 :- 4 + 10 + 16 = 30

DIAGONAL 2 :- 8 + 10 + 12 = 30.

Therefore, grid with magic number 30 is:- 4       14       12

                                                                       18       10       2

                                                                        8        6       16
