Final answer:
A typical Sudoku puzzle contains 81 squares, based on a 9x9 grid format where each row and column consists of 9 squares, and the total is calculated as 9 times 9.
Step-by-step explanation:
The answer to how many squares are on a typical Sudoku puzzle is c) 81. Sudoku puzzles are typically constructed on a 9×9 grid. Each row and column contains 9 squares, and since there are 9 rows and 9 columns in a sudoku puzzle, the total number of squares is 9 multiplied by 9, which equals 81. The purpose of the puzzle is to fill each row, column, and a 3×3 subsection which makeup the bolded boxes, with digits from 1 to 9, ensuring that each digit appears only once in each row, column, and subsection.
