Raws li wikipedia: "Ib qho dodecahedron tsis tu ncua … yog ua los ntawm 12 lub ntsej muag pentagonal tsis tu ncua, peb lub rooj sib tham ntawm txhua qhov vertex… Nws muaj 12 lub ntsej muag, 20 vertices, 30 ntug, thiab 160 kab pheeb ces kaum (60 lub ntsej muag kab pheeb ces kaum, 100 qhov chaw kab pheeb ces kaum)."
Puas yog dodecahedron yog prism?
Hauv geometry, dodecahedral prism yog a convex uniform 4-polytope. Qhov no 4-polytope muaj 14 polyhedral hlwb: 2 dodecahedra txuas nrog 12 pentagonal prisms. … Nws yog ib qho ntawm 18 convex uniform polyhedral prisms tsim los ntawm kev siv cov prisms niaj hnub los txuas cov khub ntawm cov khoom sib luag Platonic los yog Archimedean cov khib nyiab.
Dab tsi yog qhov dodecahedron?
Plato ntseeg tias thawj plaub sib raug rau cov ntsiab lus uas cov Greeks xav tias lub ntiaj teb cov khoom tsim: hluav taws, huab cua, dej thiab lub ntiaj teb. Lub dodecahedron, txawm li cas los xij, sib raug rau quintessence, lub ntsiab ntawm lub ntuj.
Lub ntiaj teb puas yog dodecahedron?
Lub Ntiaj Teb muaj cov duab ntawm hexahedron lossis lub voos xwmfab (Timaeus 54e–55b). … Txawm hais tias Plato tsis tau hais txog cov duab ntawm cov tawv tawv no, cov kws tshawb fawb pom zoo tias nws tab tom hinting ntawm dodecahedron, uas yog polyhedron ua los ntawm 12 pentagons tsis tu ncua (Fig. 17.2).
Puas yog dodecahedron Tessellate?
Lub rhombic dodecahedron tuaj yeem siv los ua tessellate qhov chaw peb sab: nws tuaj yeem muab tso rau hauv qhov chaw, zoo li hexagons sau lub dav hlau. Qhov no polyhedron nyob rau hauv ib qho chaw-filling tessellation tuaj yeem pom raws li Voronoi tessellation ntawm lub ntsej muag-centered cubic lattice.
