Exactly four faces of a rectangular solid are painted.
Column A Column B
The fraction of the surface area that is painted 2/3
选项
A、if the quantity in Column A is greater
B、if the quantity in Column B is greater
C、if the two quantity are equal
D、if the relationship cannot be determined from the information given
答案
D
解析
长方体的4个面被涂色
解:本题的正确答案为(D)。比较的左项为涂色的部分占表面的比例。长方体共有六个面,虽然有4个面涂色,但是由于不知道各面的面积大小,因而不能确定所求的比例。考生仔细考虑后就会发现,实际上,涂色的部分占表面的比例在1/2与1之间,但不能等于1/2和1。
