如图所示，轻质圆柱形容器甲、乙置于水平地面上，甲盛有质量为m的水、乙盛有质量为3m的酒精，甲、乙的底面积分别为3S、5S。（ρ_酒精＝0.8×10³千克/米³）

① 求甲容器中质量为2千克水的体积V_水。
② 求乙容器中，0.1米深处酒精的压强p_酒精。
③ 为使容器甲、乙对水平地面的压力相等，且两容器内液体对各自容器底部的压强相等，需将一实心物体A浸没于某一液体中（此液体无溢出），求物体A的质量m_A与密度ρ_A。

   Compared with other European countries, lifestyle in Italy is slower and more relaxing in its own way. Italians love to chat over a cup of coffee, go out for a walk in the middle of the day, and enjoy long lunches and dinners.
   Family is important to Italians. They can't think of spending a day without asking about their parents or children, and a weekend without a family lunch or dinner. Italians living outside their country also miss their family a lot.
