For a 10-foot-long row of shingles that are each 5 inches wide, how many shingles will be needed?

To determine how many shingles are required for a 10-foot-long row, you need to first convert the row length from feet to inches, since the width of the shingles is given in inches. There are 12 inches in a foot, so you multiply 10 by 12, resulting in 120 inches.

Next, since each shingle is 5 inches wide, you divide the total length of the row (120 inches) by the width of a single shingle (5 inches):

120 inches ÷ 5 inches/shingle = 24 shingles.

This calculation shows that 24 shingles are required to cover a 10-foot-long row. Therefore, the correct answer is 24 shingles, making the choice that reflects this calculation accurate. This process highlights the importance of understanding measurements and conversions when performing tasks related to construction or material estimation.
