<prompt> Mchemraba wa mbao, ambao kingo zake ni urefu wa sentimita moja, hutegemea uso wa usawa. Ukiwa umeangaziwa na chanzo cha nuru ambacho ni sentimita x moja kwa moja juu ya kipeo cha juu, mchemraba huo hutoa kivuli kwenye uso ulio mlalo. Eneo la kivuli, ambalo halijumuishi eneo chini ya mchemraba ni sentimita 48 za mraba. Pata nambari kamili isiyozidi 1000x.  <response>: asy kuagiza tatu; ukubwa250;kalamu-msingi0.7fontsize9; kitengo halisi 0.5; halisi r 2.8; triple O0,0,0, P0,0,unitunitr-1; nukta P; kuchoraO--P; choraO--unit,0,0--unit,0,unit--0,0,unit; choraO--0,unit,0--0,unit,unit--0,0,unit; choraunit,0,0--unit,unit,0--unit,unit,unit--unit,0,unit; chora0,unit,0--unit,unit,0--unit,unit,unit--0,unit,unit; choraP--runit,0,0--runit,runit,0--0,runit,0--P; choraP--runit,runit,0; chorarunit,0,0--0,0,0--0,runit,0; choraP--0,0,unit--unit,0,unit--unit,0,0--runit,0,0--P,dashedblueupana 0.8; lebox,0,0,unitunitr-12,WSW; lebo1,unit2,0,unit,N; lebo1,unit,0,unit2,W; lebo1,unit2,0,0,N; lebo6,unitr12,0,0,N; lebo7,unitr,unitr2,0,SW; asyKielelezo si cha kupima Eneo la msingi wa kivuli cha mraba ni 48 1 49, na hivyo pande za kivuli ni 7.
