Arrange 1, 2, 3, 4, 5, 6, 7, 8, 9 in the form of 3X3 magic square so that we get sum 15 by adding numbers from any direction (row, column diagonal)

2 9 4 7 5 3 6 1 8

Fill the Boxes with Numbers : 1 , 2 , 3 , 4 , 5 , 6 , 7 , 8 , 9 No Repetition

A magic wish-granting rectangular belt always shrinks to 1/2 its length and 1/3 its width whenever its owner makes a wish. After three wishes, the surface area of the belt's front side was 4 cm2. What was the original length, if the original width was 9 cm?

Each empty white square in the grid contains one of the numbers 1, 2, 3,..., 8. Each of the horizontal and vertical equations must be true and each number must be used exactly once.

There are four solutions.

Arrange all the digits 0, 1, 2, 3, 4, 5, 6, 7, 8, and 9 to give four different square numbers. (You make a square number when you multiply something by itself, so 49 is square because it is 7 times 7)
