Presentation Description

Table of all the important parameters of a truncated hexahedron (having 8 congruent equilateral triangular & 6 congruent regular octagonal faces each of equal edge length) such as normal distances & solid angles subtended by the faces, inner radius, outer radius, mean radius, surface area & volume calculated by using HCR's formula for regular polyhedrons. It can be used in analysis, designing & modelling of polyhedrons.

HCR’s Formula for Regular n-Polyhedrons Analysis of Truncated Hexahedron: Let there be any truncated hexahedron having 8 congruent equilateral triangular 6 congruent regular octagonal faces each of edge length a then all its important parameters are calculated as tabulated below Congruent polygonal faces No. of faces Normal distance of each face from the centre of the given truncated hexahedron Solid angle subtended by each face at the centre of the given truncated hexahedron in Ste-radian sr Equilateral triangle 8 √ √ √ √ Regular octagon 6 √ √ √ Inner inscribed radius √ Outer circumscribed radius √ √ Mean radius √ Surface area √ Volume √ When a solid truncated hexahedron of the maximum volume is produced from a solid sphere having certain diameter then approximate of total volume of the parent sphere is removed as scraps in facing operations to generate 8 congruent equilateral triangular 6 congruent regular octagonal faces each of equal edge length.
