You don't find the "volume" of a flat figure. Perhaps you want its surface area.
The area for a regular octagon of side "a" is 2 (1 + root(2)) a2, where "root" is
the square root function. If it is not a regular octagon, I don't think there is a
simple formula to find the area - you'll have to split it up into simpler figures,
for example triangles.
==================================
Answer #2:
Here is the formula, to which the first answer alluded in passing,
but which, for some reason, it did not explicitly present:
Volume of an Octagon = 0 .
an octagon doesn't have a volume its has and area ecause it is a 2-d figure. to find the area of a 2-d regular figure it is 1/2 apothem * perimeter (apothem is the distance of a line from the center of a polygon, to the midpoint of a side)
There is no formula for an octagon. There are formulas for figuring out different aspects of an octagon, such as its perimeter, diameter, etc.
the formula to find the volume for anything is to multiply length times width times height.
formula to find volume of an eccentric reducer
Formula for volume of a sphere = 4/3*pi*radius3 measured in cubic units.
an octagon doesn't have a volume its has and area ecause it is a 2-d figure. to find the area of a 2-d regular figure it is 1/2 apothem * perimeter (apothem is the distance of a line from the center of a polygon, to the midpoint of a side)
well the volume of an octagon would be different for every octagon.

The formula of volume
Calculating the volume (V) of an octagonal prism involves finding the area (A) of the octagon that is an end (or base), and then simply multiplying it by the length (L) of the prism. The area of an octagon with a side of length s is given by this formula: Aoctagon = 2 (1 + sqrt 2) s2 or about 4.8284 s2 If we take that and multiply it by the length of the prism, we should arrive at the volume thus: Voctagonal prism = L x Aoctagon
A formula is a string of letters and numbers and other mathematical characters. It has no volume.
Length x Width x Height is the formula to find the volume of a juice box.
the formula to find the volume for anything is to multiply length times width times height.
Perimeter = 8 x (length of one side)
There is no single formula. It depends on the shape of the object whose volume you are trying to find.
Volume = Length * Width * Height
