In April this year, to celebrate the 60th anniversary of the founding of the People's Navy, our submarine force participated in the naval review held in Qingdao. The total volume of a submarine is 1.8. (1) submarine buoyancy: f float = ρ seawater gV platoon =1.03x103kg/m3×10n/kg×1.8×103m3 =/.

(2) Pressure on submarine: p=ρ seawater GH =1.03x103kg/m3×10n/kg×120m =1.236x1.

Therefore, the answer is:1.854×107; 1.236× 106.
