1 TE GEOMETRY OF PYRAMIDS One of te more interesting solid structures wic s fscinted individuls for tousnds of yers going ll te wy bck to te ncient Egyptins is te pyrmid. It is structure in wic one tkes closed curve in te x-y plne nd connects strigt lines between every point on tis curve nd fixed point P bove te centroid of te curve. Clssicl pyrmids suc s te structures t Gi ve squre bses nd lterl sides close in form to equilterl tringles. Wen te closed curve becomes circle one obtins cone nd tis cone becomes cylindricl rod wen point P is moved to infinity. It is our purpose ere to discuss te properties of ll sided pyrmids including teir volume nd surfce re using only elementry clculus nd geometry. Our strting point will be te following sketc- Te bse represents regulr sided polygon wit side lengt. Te ngle between neigboring rdil lines r (sown in red connecting te polygon vertices wit its centroid is θ=π/. From tis it follows, by te lw of cosines, tt te lengt r=/sqrt[(1- cos(θ]. Te re of te iscosolis tringle of sides r--r is- A T r 1 cos( (1 cos( From tis we ve tt te re of te sided polygon nd ence te pyrmid bse will be-

2 A bse 1 1 It redily follows from tis result tt squre bse = s re A bse= nd exgon bse =6 yields A bse = sqrt( /. ext using te Pytgoren Teorem one s tt te slnted edges will ec ve lengt of- s (1 cos( To clculte te volume of tis pyrmid we envision oriontl cut troug te pyrmid t eigt bove te x-y plne. By simple geometry we ten ve tt tis produces smller sided polygon of re- A polygon 1 [1 cos( ] [1 cos( ] Applying elementry clculus to tis re we get te pyrmid volume- pyrmid const. 0 (1 d 1 1 BseAre ( 1 For squre bse pyrmid tis result predicts tt pyrmid = /. Tt is, te volume equls te bse re times te pyrmid eigt divided by tree. Tis result continues to old for ll sided polygon bses including te cone were but 0 nd te volume becomes cone =πr (/. Te side surfce re of n sided regulr pyrmid cn be clculted by looking t te individul iscosolis tringles of sides s--s, wit s being te slnt eigt given erlier. Te totl surfce re produced by tese tringles is-

3 A sides 1 cos( 1 cos( Te simplest pyrmid is found wen =. It corresponds to stndrd tetredron wen te eigt bove te x-y plne is set to sqrt(/. Tis represents figure composed of four equl equilterl tringles of side lengt ec. One possible configurtion s te four vertices locted t [[/, /(sqrt(, 0], [-/, /(sqrt(, 0], [0, -/sqrt(, 0], nd [0, 0, sqrt(/].te volume of tis tetredron is tetredron = /[6sqrt(]= nd te totl surfce re including te bottom is A tetredron =sqrt( = ext let us exmine te world s best known squre bsed pyrmid structure, nmely, te Gret Pyrmid of Ceops(lis Kufu found t Gi, Egypt. Tis is most impressive structure built bout 600BC. Its bse lengt is =775.8 ft nd eigt =81. ft. Te four sides re in te spe of iscosolis tringles wit te edges ving te lengt of s=719. ft. Tt is, te sides differ sligtly from equilterl tringles wic would require eigt of =/sqrt(=58.6 ft. Undoubtedly te pyrmid builders were worried bout pyrmid stbility nd cost by coosing to go for smller eigt tn required for true squre bse pyrmid wit equilterl tringle sides. Te volume of te Gret Pyrmid cn be clculted using te bove given dimensions nd is- (775.8 (81. Ceops (1/ million cubic feet To be ble to cut nd move tis mount of stone in te estimted 0 yer building time for te gret pyrmid is indeed n ming fet considering te builders were working witout te id of mcines or nimls oter tn te umn lbor of tousnds. An interesting ppyrus found t te lley of te Kings ner Luxor sows tt te ncient Egyptins were quite fmilir wit te properties of squre bsed pyrmids. In prticulr te so-clled Moscow Ppyrus sows tt te builders lredy knew some 000 yers go tt te volume of truncted pyrmid(frustrum equls- frustrum ( b b,were is te eigt of te truncted pyrmid, te bse side lengt, nd b te side lengt t te top level. Tis formul ws derived witout te id of clculus nd clerly sows tt te rcitects knew tt te volume of ny squre bsed pyrmid of eigt

Let us derive te Moscow Ppyrus result by noting tt truncted pyrmid s volume- 1 1 b ( 1 1 (1 since b/=1-(/. On furter expnding we find- ( b b b b in greement wit te ppyrus result. Wt te builders obviously knew is tt te mjority of te stone volume is locted in te bottom portion of pyrmid. Tey knew tt wen reced lf te finl eigt, so tt b=/, full 7/8 t of te pyrmid stones were lredy in plce (ie. frust / totl ={1-(1-1/8 }=7/8.Te Gret Pyrmid of Ceops s 10 lyers of stone, so tt wen tey got to te 105 t lyer only 1/8t of te stone volume still needed to be instlled. If you ever get cnce to trvel to Egypt be sure to visit te pyrmids t Gi. Tese structures re indeed n impressive sigt. I remember visiting tem nd te Spinx severl decdes go. Except for te oppressive outside summer et nd te ig umidity inside te pyrmids, it ws n unforgettble experience. My understnding is tt in te lst few dys te Stte Deprtment s dvised tourist from going tere becuse of lck of police protection for trvelers nd politicl instbility in Egypt. Finlly it sould be pointed out tt tere re mny oter pyrmidl structures wose bses re not regulr polygons nd were point P t = does not lie directly bove te bse centroid. All tt is required is tt one cn express te cross-sectionl re of cut troug te structure t eigt to obtin te pyrmid volume vi simple clculus. Tke, for instnce, te volume formed by te slnted plne x+y+=1 nd te x=0,y=0, nd =0 plnes. Te bse re is ere ½ nd te eigt is 1. Tus te volume is =(1/(1/=1/6. A more complicted structure, reminiscent of some of te Cinese nd Jpnese pgods, involves squre bse of re wit curved sides merging t point t =. In tis cse one s pyrmid volume of-
