解:120cm^2=0.012m^2;8cm=0.08m; (1)p水=1000kg/m^3;g=10N/kg; V排=V-1/3V=2/3Sh=2/3*0.012m^2*0.08m=0.00064m^3 物体重力G1=F浮=p水gV排=1000kg/m^3*10N/kg*0.00064m^3=6.4N; (2)原水高度h=25cm=0.25m; 水升高度h2=V/S容=0.00064m^3/(0.5m*0.5m)=0.00256m P=p水gh=p水g(h1+h2)=1000kg*10N/kg*(0.25m+0.00256m)=2525.6Pa (3)水面高度:h=h1+h2=0.25m+0.00256m=0.25256m
