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.
Area in square feet = pi*radius2
36 sq feet- height of the room does not matter when figuring out square footage
Square footage is a measure of an area. It is usually for areas for which square feet is a sensible measurement unit, such as a room, or a house. However, we have had people asking about the square footage of countries!
Length x width = square footage
Square footage of a building usually refers to the total square footage of floor area.
length x width of each roof segment.
There is no formula for the square root of a number, unfortunately.
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...

If you mean a circle then its square footage formula is: pi*radius2
Treat it as a square and half the result.
Length x width. If you are figuring egress, you can only measure the actual opening size.
Area in square feet = pi*radius2
roughly 240 square feet. Formula for figuring yardage is: (Width X Length X thickness)/27= cubic yardage of concrete. Just reverse the formula to solve for Width X Length or Square Feet. CY X 27 divided by thickness = square footage
length x width = area (sq. foot)
length x width = area
To calculate square footage of a pipe you need to use the area formula of a circle, a=1/2bh. then find the circumference of the entire pipe.
