An octagon is a square with the corners cut off, so it has 8 equal sides and all angles are the same, like an American Stop sign. If each edge of an octagon is 1 foot, then the area is 4.828 square feet (2+2root2). For an octagon with an edge length of x feet, the area would be 4.828 times x squared.
To turn a 9x9 square into an octagon you can cut corners off the square. It will not be a regular octagon though.
You don't. Its cubinc footage, not square footage.
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.

The square footage of a lot measuring 81x180x113x180 is 20,340 square feet. Square footage is found by multiplying the length by the width of an area.
133.08ft2
you have to treat it like a square then subtract the missing areas
The area of an octagon with each side being 8 feet is 309 square feet.
44499 sq ft (approx)
Length x width = square footage
In order to calculate the square footage you need to find the length and the width of the room in feet. You multiply the length and the width to give you the square footage of the room
The formula for the area of an octagon is Area = (2 + 2√2)a2, where a is the length of each side. Area = (2 + 2√2)12ft2 = 695ft2
You can't, a hole has volume and thefore needs to be measured in cubic footage. Square footage is a measure of area not volume.
To find the square footage you should multiply the length and width of each room, and add up the results to give you the total square feet.
length x width
Area in square feet = pi*radius2
The answer depends on whether or not the octagon is regular and also on what information about its side lengths, angles, etc you have.
