超正方体的体积计算公式

Floor 1 218.88.141.* 3/18/11 22:03
V4=a^4
Floor 2 218.88.141.* 3/18/11 22:06

1cm4=10000mm4(也就是1e4mm4)

1dm4=1e4cm4

1m4=1e4dm4

1hm4=(1e4)^2=1e8m4

1km4=1e12m4

Floor 3 218.88.141.* 3/18/11 22:06
1四次方千米就是1000000000000四次方米!
Floor 4 218.88.141.* 3/18/11 22:38

棱长是3dm的超正方体,体积是:

V4=3^4=81(dm4)

Floor 5 116.233.112.* 4/19/11 21:18
二维我们说面积    三维我们说体积     那四维呢   
Floor 6 4Der 4/19/11 21:30
四维就是m4,dm4,cm4,进率为10000
