标题: og 12 ds122
what is the volume of a certain rectangle solid?
1.two adjacent faces of the solid have areas 15 and 24,respectively
2.each of two opposite faces of the solid has area 40
我想问2的意思是什么?我的理解是solid任意相反两面的面积是40.那么这个solid就应该是正方体啊,所以我选了B。。正确答案是E

我的理解是某一组相反两面里每个面的面积都是50

如果按lz的理解应该是each of every two opposite faces blah blah blah吧我猜
