A 3×3 grid There are 9 + 4 + 1 = 14 total squares.
How many squares can be made from a 3×3 grid?
3×3. a 3×3 grid has 9 1×1 (3 * 3) squares 4 2×2 (2 * 2) squares and a single 3×3 square = 14. a 3×4 grid has 12 1×1 (3 * 4) squares 6 2×2 (2 * 3) squares and 2 3×3 squares = 20. Again, if you continue this you can find that a 3 x m grid has 3*m + 2*(m-1) + 1*(m-2) squares.
How do you find the number of squares on a grid?
To get the total number of squares we need to find all the squares formed.
- x 1: 8 * 8 = 64 squares.
- x 2: 7 * 7 = 49 squares.
- x 3: 6 * 6 = 36 squares.
- x 4: 5 * 5 = 25 squares.
- x 5: 4 * 4 = 16 squares.
- x 6: 3 * 3 = 9 squares.
- x 7: 2 * 2 = 4 squares.
- x 8: 1 * 1 = 1 square.

How do you do the 3×3 magic square?
So, if you have a 3×3 square, place the number 1 in Box 2 of the top row; in a 15×15 square, place the number 1 in Box 8 of the top row. Fill in the remaining numbers using an up-one, right-one pattern. You will always fill in the numbers sequentially (1, 2, 3, 4, etc.)

How do you print a grid in Python?
Make it a function
- Write a function print_grid(n) that takes one integer argument and prints a grid just like before, BUT the size of the grid is given by the argument.
- For example, print_grid(9) prints the grid at the top of this page.
- print_grid(3) would print a smaller grid:
- print_grid(15) prints a larger grid:
