90
When a number is squared, it means that it is that number is multiplied by itself. So in this case it would be 9x9 which is equal to 81.
Your square footage is the length and width or 9x9 or 81sq ft. For cubic you need to include another measurement, that would be the depth. For instance if you want the depth to be 9ft also then your cubic measurement would be 9x9x9 or 729 cu ft.
A 9x9 foot slab 4 inches thick requires a minimum of 1 cubic yard. If you go to 6 inches thick you will need 1.5 cubic yards.
The square footage is 81 sq ft (9 x 9). Note, if you are buying flooring materials, you will need to get more - probably at least 10% waste which will bring you to around 90 sq ft. (it could be more for carpet since you need to order in 12 ft rolls - prob 111sf needed)
The mechanics involved in sudoku follow the principal, that any 3x3 grid can be filled with the numbers 1-9, every row can have 1-9, and every column can have 1-9, to eventually have a complete 9x9 grid filled with the numbers 1-9, where no numbers in any row, column, or 3x3 grid have two of the same number

A Sudoku can have a non-unique solution with only 4 empty cells. Here's an example: 003496758 587132469 694875213 008763945 946581327 375924186 761259834 852347691 439618572 If the first 2 cells are filled with 1,2 the 2 in row 4 must be 2,1, and vice-versa. So there can be up to 77 givens in a 9x9 sudoku without a unique solution.
wordoku, sudoku using symbols, different sizes (4x4, 6x6, 9x9, 16x16) plus differently shaped puzzles and the "samurai" (5 interlocking 9x9 boxes) ----those are really REALLY HARD!!!
"Sudoku" is a puzzle game that originated in Japan. It involves filling a 9x9 grid with numbers so that each row, each column, and each of the nine 3x3 subgrids contains all the numbers from 1 to 9 without repeating.
Actually, there is more than 81 squares. SQUARE SIZES Multiplication to do: 1x1=81 ---> 9x9 2x2=64 ---> 8x8 3x3=49 ---> 7x7 4x4=36 ---> 6x6 5x5=25 ---> 5x5 6x6=16 ---> 4x4 7x7=9 ---> 3x3 8x8=4 ---> 2x2 9x9=1 ---> 1x1 now add up all products or amount of squares for each size.....and you get? 285!!! there are 285 squares inn a 9x9 grid.
Assuming 9x9 is also in feet, then answer is 81 square feet.
The code is below and i should also explain the algorithm. Well, What we are doing here is that we already defined the size to be 9x9 sudoku and are getting values using loops. All the empty spots are given UNASSIGNED value. Then we have functions to tell that if it is safe to put a value in the empty box by calculation and according to the rules of Sudoku it checks for is there any other some number horizontally and vertically and do the sum of the row and column is less than or equal to required or not. If the functions returns true then the program puts the value there.#include #define UNASSIGNED 0#define N 9bool FindUnassignedLocation(int grid[N][N], int &row, int &col);bool isSafe(int grid[N][N], int row, int col, int num);bool SolveSudoku(int grid[N][N]){int row, col;if (!FindUnassignedLocation(grid, row, col))return true; // success!for (int num = 1; num
81 1 9x9, 4 8x8, 9 7x7, all the way to 81 1x1. So it is 12 + 22 + 32 +...... + 92 =285
9x9=81
