I am a designer / estimator for a general Contractor in Charlotte NC. I've just finished estimating a screened porch addition @ approx. $68 per square foot. Another one I did last week came to $97 per foot. It depends on the materials to be used and the overall size. A smaller porch would be much higher per square foot than a larger one due to the fact that the same amount of sub contractors would be involved but each would have a higher per foot rate for a smaller job thus driving the average $ per foot up. This link has an excel spreadsheet that is very user friendly for generating estimates. Just plug in the info and let it do the work. It even breaks down pricing if you do it yourself vs. hiring a contractor. Check it out.http://www.composite-decks.com/GeoDeck-samples-literature.htm
To calculate the volume of a house, you multiply the floor area by the ceiling height. For a house with 3,500 square feet of floor space and 9-foot ceilings, the volume would be 3,500 square feet × 9 feet, which equals 31,500 cubic feet.
10' by 10' with 8-ft ceilings: -- Floor = 100 square feet -- Ceiling = 100 square feet -- Each wall = 80 square feet Total interior surface area of the room = (2 x 100) + (4 x 80) = 520 square feet. (Less windows, recessed light fixtures, doors, electrical outlets, etc.)
12' by 12' with 9-ft ceilings: -- Floor = 144 square feet -- Ceiling = 144 square feet -- Each wall = 108 square feet Total interior surface area of the room = (2 x 144) + (4 x 108) = 720 square feet. (Less windows, recessed light fixtures, doors, electrical outlets, etc.)
If the square footage refers to floor area, yes.
To find the length of each side of the square floor, you need to take the square root of the area. Since the area is 324 square units, the square root of 324 is 18. Therefore, each side of the square floor is 18 units long.
In short "YES" Real estate appraisers normally determine the square footage of a home by measuring the exterior of the building. If a home has two floors, the appraiser may just calculate the living space as being twice the size of the ground floor's dimensions. If you have a two-story home with vaulted ceilings, you actually have less usable square footage than someone with an identically sized home that does not have vaulted ceilings. Nevertheless, appraisers typically do not deduct the square footage you sacrificed when you chose to install vaulted ceilings. This means that in terms of usable square footage, homes with vaulted ceilings normally cost more than homes without vaulted ceilings.
To calculate the volume of a house, you multiply the floor area by the ceiling height. For a house with 3,500 square feet of floor space and 9-foot ceilings, the volume would be 3,500 square feet × 9 feet, which equals 31,500 cubic feet.
To calculate the square footage of a room, you multiply the length by the width. For a room that is 20 feet by 30 feet, the square footage is 20 x 30 = 600 square feet. The height of the ceilings does not affect the floor area, so the room remains 600 square feet regardless of the ceiling height.

do you mean floor square foot or actual wall sqare foot?...as a rule of thumb here in Ok, I usually charge about 2.50 (floor sq ft ) as a ballpark estimate for complete repaints (walls and ceilings)
In northern Upstate regions, Yaros Painting charges $2.85 per square foot of floor space in rooms with 8ft ceilings, provided that the walls and trimming do not require extensive preparatory work. This covers all of the preparation, priming, and painting of walls, trim, and ceilings.
That would depend on how tall it is. For example, a house with 8 foot tall ceilings and 4000 square feet floor space, would hold:(4000 ft2)x(8 ft) = 32000 ft3If it had 10 foot ceilings, then: (4000 ft2)x(10 ft) = 40000 ft3
If the floor area is 313 square meters, then the floor area is 313 square meters.
The floor's area is: 1,296 square feet.
The standard chair rail molding height for a room with 8-foot ceilings is typically around 30 inches from the floor.
