问题
The dimensions, in centimeters, of rectangular box R are 6 by 8 by 10. Which of the following CANNOT be the total surface area, in square centimeters, of two faces of R?
选项
A、96
B、120
C、128
D、160
E、180
答案
E
解析
以厘米为单位,长方体盒子R的尺寸为6×8×10,请问下列哪项不能是R的两个面的面积的和(以平方厘米为单位)?
解:本题的正确答案为(E)。长方体盒子有六面,且对面两两相等,共有三个面积不同的面,分别是6×8=48,6×10=60和8×10=80,这些面两两相加,包括与自身相加,共有6个不同的取值:分别是:96,120,160,108,128,140。把这些值与题目的选项对照,发现(E)不等于长方体盒子两个面的面积的和。考生也可用另一种方法来解此题,在长方体中面积最大的一面为8×10=80,所以两个最大面的面积和最大为160,因此180显然不能是长方体两个面的面积的和。
