a roofing square is 100 sf. There are formulas out there that allow you to use the pitch and outer dimensions of the roof to figure out the number of squares. If not, calculate the square footage and divide by 100 - that's the number of squares you have...
1 roofing "square" = 100 square feet. 100 square feet = one square
In roofing, it is the weight of the roofing in pounds per 100 square feet of coverage.
A roofing square covers an area of 100 square feet. A standard 4x8 sheet measures 32 square feet (4 feet x 8 feet). To determine how many 4x8 sheets are in a roofing square, divide 100 square feet by 32 square feet, which equals approximately 3.125 sheets. Therefore, you would need about 4 sheets of 4x8 to cover a roofing square, accounting for waste and cuts.
There is no formula for an octagon. There are formulas for figuring out different aspects of an octagon, such as its perimeter, diameter, etc.
[(Linear feet x 12) / 16] + 1 is the formula.
There is no formula for the square root of a number, unfortunately.
length x width of each roof segment.
In roofing terminology, a "square" is 100 square feet; of 9.29 square meters.
1 roofing "square" = 100 square feet. 100 square feet = one square
The formula for calculating square footage is a=S2 (a = area and s = side) Example, to calculate the square footage of a room that is 15 feet wide and 12 long, you would multiply 15 x 12, which will give you the square footage.
Since A = s^2, then s = square root of A. Ex: If A = 9, then s = sqrt (9) = 3.
In roofing, it is the weight of the roofing in pounds per 100 square feet of coverage.
If I recall from my roofing days, a square is 3 bundles of shingles. Those 3 bundles cover 100 of square feet.
T=Square Root of 2(d)/a d=distance a=acceleration due to gravity= 9.8m(given)
1 square of roofing shingles is 3 bundles of shingles equaling 63 shingles per square.
10ft. By 10ft.-100 square feet
Per square what? (Metre? Foot?) You haven't fully asked the question. A "square", when referring to roofing and siding, is 100 square feet.
