12-413: A 2 ≈ 9.173 a 2 . {\displaystyle {\frac {8+2{\sqrt {3}}+{\sqrt {5+2{\sqrt {5}}}}}{2}}a^{2}\approx 9.173a^{2}.} Its volume can be obtained by slicing it into a regular pentagonal prism and an equilateral square pyramid, and adding their volume subsequently: 233 + 90 5 + 12 50 + 20 5 12
18-417: A pentagonal prism by attaching an equilateral square pyramid to one of its square faces, a process known as augmentation . This square pyramid covers the square face of the prism, so the resulting polyhedron has four equilateral triangles , four squares , and two regular pentagons as its faces. A convex polyhedron in which all faces are regular is Johnson solid , and the augmented pentagonal prism
