设俄罗斯积分供罚垛核艹姑讹太番咖为X我国积分则为3X+1
可得公式3X+1+X=11
可得出X=2.5
则俄罗斯积分2.5
我国积分8.5
为什么等于11
因为他们总共进行了11盘啊，仔细看题！看题啊小盆友

-CE&#178，所以BCDE为正方形;2=3√2
因为AE⊥平面BCDE，DO=BD&#47，∠CDE=90°
已知∠BCD=90°;=36;2=18√2
因为CG=2GA，AE=6
ACE面积=AE·CE&#47，所以CE=BD=√2·BC=6√2，已证明BD⊥平面ACE，所以AE⊥CE，DO为高的三棱锥D-CEG
BCDE为正方形，所以BC⊥平面ABE，AE⊥CD
因为∠ABC=90°，AD⊥CD，CE⊥BD
因为AE⊥平面BCDE，∠CBE=90°
同理，CD⊥DE，因为∠CDA=90°，BCDE为长方形
又因为BC=CD;2=6X6√2&#47，所以CD⊥平面ABE，AE&#178;=(6√3)&#178，所以AE⊥BC，所以AE⊥BD，BC⊥BE;3=12√2
三棱锥E-GCD体积=s·h/=AC&#178;-(6√2)&#178，G在AC上，所以∠BED=90°，所以CGE面积=2面积AGE，CGE面积= ACE面积X2&#47，AB⊥BC，则DO⊥平面AGE
三棱锥E-GCD可看做以CEG为底，所以BD⊥平面ACE（2）设BD和CE交点为O（1）因为AE⊥平面BCDE;3=12√2X3√2&#47
