How many square feet of shingles are in a bundle of architectural shingles, assuming that there are three bundles to a square?

1. 33 1/3

2. 25

3. 100

4. 50

The correct answer is: 33 1/3

In roofing terminology, a "square" refers to an area of 100 square feet. Architectural shingles, commonly used in roofing due to their durability and aesthetic appeal, are typically sold in bundles. When it comes to architectural shingles, it is standard for there to be three bundles required to cover one square. To determine how many square feet are in one bundle of architectural shingles, you can divide the total square footage covered by a square (100 square feet) by the number of bundles per square (which is three). Calculating this gives: 100 square feet / 3 bundles = approximately 33 1/3 square feet per bundle. This calculation supports the assertion that each bundle of architectural shingles effectively covers about 33 1/3 square feet. Understanding this concept is critical, as it directly impacts ordering materials, budgeting for roofing projects, and ensuring adequate coverage on existing structures.
