9 bundles assuming std. 3 bundle/sq. shingles
Most shingles come 3 bundles per square(100 sq. ft.), so you would have 4200 bundles for 1400 sq, but only 42 if you are asking about 1400 sq. ft.
typically a square is three bundles (about 26 shingles per) but in some types of architectural shingles there are four bundles per square to make them easier to handle.
To determine how many bundles of roofing shingles are needed to cover 2,100 square feet, you first need to know that one bundle typically covers about 33.3 square feet. Dividing 2,100 by 33.3 gives you approximately 63.1 bundles. Since you can't purchase a fraction of a bundle, you would need to round up to 64 bundles to ensure complete coverage.
