You have a total roof area on each side of a gable roof of 44 feet by 18 feet. The shingles chosen have three bundles per square. How many bundles of shingles are needed to cover this roof, NOT including waste?

To determine the number of bundles of shingles needed to cover the gable roof, it is essential first to calculate the total square footage of the roof.

Each side of the gable roof has an area of 44 feet by 18 feet. Therefore, for one side of the roof, the area is calculated as follows:

Area = Length × Width

Area = 44 feet × 18 feet = 792 square feet.

Since there are two sides to the gable roof, you will multiply the area of one side by two:

Total Area = 792 square feet × 2 = 1584 square feet.

Now, shingles are typically sold in squares, and one square of roofing material covers 100 square feet. To find the total number of squares needed to cover the roof, you can divide the total area by 100:

Total Squares = Total Area / 100

Total Squares = 1584 square feet / 100 = 15.84 squares.

Since shingles come in bundles and you need a whole number of bundles, you will round up to account for any partial square needed. With three bundles covering one square, you multiply the number of squares needed by the number of bundles per square:

Total Bundles = Total Squares
