9).cubul are 12 muchii.=> Suma muchii=12×6=72cm; 10).suma muchii=60=>muchia cub =60÷12=5cm. 11).Suma muchii(Sm)=48=>4l+4L+4h=48=> 4(l+L+h)=48=>l+L+h=12; L=l+1;h=l+2;=> l+l+1+l+2=12<=>3l+3=12<=>3l=12-3 <=> 3l=9=>l=3. L=l+1=3+1=4;h=l+2=3+2=5;{l=3cm,L=4cm,h=5cm}. 12).L^3=3^3=27; l^3=1^3=1;27÷1=27cuburi
