    解:设截取圆钢的长度为xmm.根据题意,得π(902)2x=131×131×81,解方程,得x=686.44π.答:截取圆钢的长度为686.44πmm.方法总结:圆钢由圆柱形变成了长方体,形状发生了变化,但是体积保持不变.“变形之前圆钢的体积=变形之后长方体的体积”就是我们所要寻找的等量关系.探究点三:面积变化问题将一个长、宽、高分别为15cm、12cm和8cm的长方体钢坯锻造成一个底面是边长为12cm的正方形的长方体钢坯.试问:是锻造前的长方体钢坯的表面积大,还是锻造后的长方体钢坯的表面积大?请你计算比较.解析:由锻造前后两长方体钢坯体积相等,可求出锻造后长方体钢坯的高.再计算锻造前后两长方体钢坯的表面积,最后比较大小即可.解析:设锻造后长方体的高为xcm,依题意,得15×12×8=12×12x.解得x=10.锻造前长方体钢坯的表面积为2×(15×12+15×8+12×8)=2×(180+120+96)=792(cm2),锻造后长方体钢坯的表面积为2×(12×12+12×10+12×10)=2×(144+120+120)=768(cm2).
