When talking roofing materials. A square is considered a 10'x10' area or a 100 square feet. So you have 1,900 square feet. There are two basic types of felt: 15lb and 30lb felt. 15lb felt covers 4 sq= Total needed will be 5 rolls 30lb felt covers 2 sq= Total needed will be 10 rolls (*note, 30lb is more thick and better for your roof.
4 squares per roll works for me. 15# felt- 6 rolls, 30# felt- 12 rolls.
Enough to cover the roof. 15 lb. covers 400 sq. ft. per roll. 30 lb. covers 200 sq. ft. per roll.
310.5 sq ft
13 ft by 23 ft = 299 ft2 and one standard sheet of plywood is 4 ft by ft = 32 ft2. 299 / 32 = 9.34 sheets, so you will need to purchase 10 sheets of plywood.
23 square feet = about 2.14 square meters. (2.13676992 square meters)
One sheet (4 ft x 8 ft) = 32 ft2 You might need to cut the sheet to fit in the specific space you have, but one sheet will have enough material to cover 23 square feet.
Two.
0.23 acres is 10,018.8 square feet.
943 sq ft 9 and 1/2 squares of roofing
There are 3 bundles of shingles in every square. A square is 100 square feet. In 23 bundles, you would have 766 square feet approximately
0.23 acres is 10,018.8 square feet.
23 square feet = about 2.14 square meters
It is: 23 times 23 = 529 square feet
