In a square array, the number of students per row is equal to the number of students per column. If there are 56 students in one row, there must also be 56 rows, because the array is square, and the dimensions of a square are equal.
To find the total number of students in a square array, you multiply the number of students in one row by the number of rows. Since both the row count and student count per row is 56, the calculation is as follows:
Total number of students = Students per row * Number of rows
Total number of students = 56 * 56
Now, let's do the multiplication:
56 * 56 = 3136
Therefore, there are 3136 students altogether arranged in the square array.
