If an octagon has a height of 17' and a base of 13'6" then it is not a regular octagon. In that case, a lot more information is required before its area can be calculated.

How do you find surface area and volume of an octagonal prism?

If the octagon at the base is regular, the side of the octagon is s and the height of the prism is h, the area of each octagonal base (Ab) is Ab = 2(√2 +1) s2 The perimeter of the octagon is P = 8s Then the surface area of the prism is As = 2 Ab + Ph The volume of the prism is V = Ab h
