Tricky. You need to flatten out the surface to work it out. Depends on the shape - if it's like a hemisphere then you can use the properties of a sphere - volume = 4/3 Pi R3 and surface area = 4 Pi R2 so if your dome is like half a sphere then its surface area = 2 Pi R2 and you can measure the radius R so can work it out!
if you know the footage say its 15 feet wide and 19 long than you just multiply it and thats the SQUARE FOOTAGE of the area so that
Length X width divided by 9 = sq.ft.
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.
You can find the square footage of any shape, including a dome, by taking a few measurements in relation to its base. The base of any dome is typically a circle, and because of this, the measurement you must take to find the square footage is the radius.
Multiply by 144
To figure out the square footage of this odd sized room, you simply need to multiply the numbers. The answer is 2720 square feet.
For a parking lot to have 3 measurements, it must be an unusual shape. We would need more information to figure the square footage.
I use algebra to figure square footage, cubic footage, and angles when building, It is very important.
Multiply the length times the width.
if you know the footage say its 15 feet wide and 19 long than you just multiply it and thats the SQUARE FOOTAGE of the area so that
The area is 8*6 = 48 square feet
You figure out the square footage, and then the size and number of boards needed.
You must know the total square footage of the area you need siding for. Once you know the square footage, any sales outlet can help figure the amount of siding needed. The square footage can be calculated using the length of the wall multiplied by the height of the wall.
The first thing you will need to do is measure the square footage of the area. Once you know the square footage figure on average $50 per sq foot.
Length X width divided by 9 = sq.ft.
