Answer to Problem 26AYU
Solution:
, , , , ,
Explanation of Solution
Given:
;
Calculation:
It's a rectangular prism with all edges parallel to coordinate axes. So the two endpoints of each edge must have two coordinates the same, and the third coordinate different.
For all eight vertices, there will be only two values for each coordinate. We're given those values, so all we need is to figure out the other six combinations. The easiest way to generate them is to combine each pair of coordinates for each of the given points with the other possible value for the other one.
So we generate coordinates for three vertices using pairs from :
[changing the first one].
[changing the middle one].
[changing the last one].
We get the other three by using a pair from for each:
