This result of the microstructural morphology was observed in SEM showed a typical structure of a quasicrystalline grain in the shape of a pentagonal prism, structure in the form of a ladder and surrounded by small cauliflower nodules, according to Figure 2.
The morphological analysis of [Al.sub.63][Cu.sub.25][Fe.sub.12] alloy performed by SEM, presents a crystallite with a structure of the column structure in the shape of a pentagonal prism with small platelets of aluminum oxide ([gamma]-[Al.sub.2][O.sub.3]) surrounded in the upper part and with small nodules of cauliflower.
Shien Gooi's concept is for multiple boxes shaped like a pentagonal prism

Among the technological surprises were the complement of nine small full-range drivers in an pentagonal prism
shaped enclosure, the placing of the nine drivers so that eight of them fired back and away from the listener, and the inclusion of an electronic equalizer to shape the signal that would be fed to the 901 system.
I asked each group to create at least one model of a triangular prism, rectangular prism, pentagonal prism
, and hexagonal prism.
Next build a collection of prisms: a triangular prism, a square prism, a pentagonal prism
, and a hexagonal prism.
