Question

anonymous · Answer

How many 3-inch lengths along the height and how many across the
width? Multiply them together for your total count.

First find out the area of the sheet of cardboard. Which will be 10*18 = 180 square inches. Find the area of one square to be cut. This will be 3*3 = 9 square inches. Divide 180 by 9 to get maximum number of squares. You will get 20. Your answer is 20 squares. Done!

I do not think you can get 20 squares, although the number of square inches is correct, you have to cut three lines perpendicular to the 10-inch  side and six perpendicular to the 18-inch side, giving you 3 x 6 = 18 not 20.
