#### Octogonal prism Area, Volume & Surface Area Calculation

Calculates the octagonal-prism area, octagonal-prism volume and octagonal-prism surface area for given side length(a), height(l) and distance(d) using the following formulas:

Area (A) = 2 X side-length(a) X distance(d)

Volume (V) = Area(A) X height(l)

Surface Area (SA) = (2 X A) + (8 X a X l)
