Octagonal Prism surface Area Formulas

*

Octagonal Prism surface Area Formula: 8al+ 4adWhere:a = the length of an octagon edgel = the length of the octagonal prismd = the width of one octagon face

Notice that the first and second formulas room actually the same, since:

R =al

B=2ad

Instead that 8R +2B, us get: 8(al) + 2(2ad) which is equal to the 2nd formula: 8al+ 4ad

Octagonal Prism Volume Formulas

*

Octagonal Prism Volume Formula: Volume =BlWhere:B = the Area of an Octagon Facel = the length of the octagonal prism

Octagonal Prism Volume Formula: Volume =2adlWhere:a = the size of an octagon edgel = the size of the octagonal prismd = the broad of an octagon face

Notice the the first and second formulas space actually the same, since:

B=2ad

Instead that Bl, us get: (2ad)l i beg your pardon is equal to the second formula: 2adl

Vertices, Faces, and Edges

An octagonal prism has actually 16 vertices, 10 faces, and also 24 edges.
