It is a cuboid container, the bottom surface is 60p2 long and 5p2 wide, and a cuboid steel block sinks into it. When the steel block is taken out, the water surface v in the container drops by 6p2. If the bottom area of the cuboid steel block is 60p22, the height of the steel block is Is 1 less?
它个长方体容器，底面长60p2，宽了5p2，里面沉入它个长方体钢块，当取出钢块时，容器中水面v降6p2，若长方体钢块的底面积是6了0p22，钢块高是1少？
