Problem 13. The table has 30 boxes. We paint all the boxes in row 3, all the boxes in row 6, all the boxes in column C, and all the boxes in column D. How many  boxes will not be painted? The first thing to realize that each cell is in a row and in a column, so we cannot just count how many cells are in a row and a  column. Instead, we're going to actually color them in and then we can do our counting. So let's color in row 3, then row 6, and column C, and D. Now let's  count how many boxes are not painted. 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12. There are 12 unpainted boxes, so the answer is C.

Video Summary

In the problem, a table with 30 boxes is described. To solve how many boxes remain unpainted after painting all boxes in rows 3 and 6, and columns C and D, the boxes are visually counted to ensure accurate results by avoiding double counting painted areas. After painting these specified rows and columns, 12 boxes remained unpainted. Thus, the final solution concludes there are 12 unpainted boxes.
