1、先得出一个面的面积：8÷6=8/6=4/3。要把这个正方形分成8个小正方形(可以画个草图，理解）那么每个面平均分成4份。所以得出新的小正方形的每个面的面积是 4/3÷4=1/3
所以：整个表面积是;1/3×6=2
2、本题需画线段图理解，从题意中发现，兄弟两人一共行走的路程是2个学校到家的距离。
兄行驶的时间：7时25分-7时-5分=20分
弟行驶的时间：7时25分-7时=25分
学校到家的距离：（100×20+60×25）÷2=1750（米）
3、甲参：乙没=1:3 甲参=（1/3)乙没
乙参：甲没=1:4 乙参=(1/4)甲没
甲总=甲参+甲没
乙总=乙参+乙没
甲参+甲没=乙参+乙没
（1/3)乙没+甲没=(1/4)甲没+乙没
解得 甲没：乙没=8:9
4、本题关键的是要求出鸽子飞行到两车相遇的时间。鸽子飞行的时间刚好与两车相遇的时间相同。
相遇时间;442÷（40+45）=5.2(小时）
鸽子飞行的路程;50×5.2=260(千米）
5、本题的关键是求出剩下的120个零件占总量的分率。第一天完成了总量的3/7，那么
第二天就应该完成总量的：1-3/7=4/7（而4/7刚好是6箱，可以求出每一箱的分率）
第二天每一箱占总量的：4/7÷6=2/21（第一天每个箱子所占总量的分率与第二天相同）
第一天剩下的120个所占总量的：3/7-4×2/21=1/21
用120个除以它所占总量的分率，可以得出总量：120÷1/21=2520(个）
6、
1.设正方体的边长为X，则它的表面积为6x*x=8，则x=2/3根号3，则小正方体的边长为1/3根号3，表面积=6*1/3根号3的平方=2
2.设弟弟走了x米，哥哥返回途中又走了Y米后于弟弟相遇，那么哥哥走的是x+y+y=（25-5）*100
弟弟走的是x=25*60
解得x=1500，y=250，学校离家=x+y=1750
3.设甲班参加的为x，乙班参加的为y，那么甲班没参加的是1-x，乙班没参加的为1-y，x=1/4(1-y)
y=1/5(1-x)，将等式二 y=1/5(1-x)代入等式一中得到x=4/19,将x=4/19代入等式二中得y=3/19， 那么甲班没参加的人数15/19,乙班没参加的人数为16/19，答案是15/16
4.鸽子，甲车，乙车用的时间都是一样的，设为x，40x+45x=442，x=5.2, 50*5.2=260
5.设零件共有x，每箱能装y个，3/7x=4y+120,4/7x=6y 得到x=2520，y=240，所以零件共有 2520
6.可能，4棵树各自在四条边的中心点上
1: 2平方米；
2: 1600米；
3: 15/16；
4: 260千米；
5: 2520个；
6: 可能，四棵树作为正方形池塘四条边的中心；
2 1600 15/16 260 2520
一个棱形里面一个 正方形 正方形的四个角 上的树
1: 2
2: 1600
3: 15/16
4: 260
5: 2520
6: 可能
