Is that correct?
ignore this ....
We can count. Fix the blue side of the cube to be on top. The 2 reds can be 1 on bottom and 1 on the side. 1 on the side and the next adjacent to it. 1 on the side and 1 opposite it. The greens fill up all the other sides. All other possibilities can be rotated to one of these. So there are 3 distinct cubes.
Cool! it's always interesting to have multiple ways to solve a question.
I got the same answer.
Haha No problem
Oops just ignore this
000/7 = 142 numbers that have at least 1 factor of 7
1000/49 = 20 numbers that have at an additional factor of 7
1000/343 = 2 numbers that have a third factor of 7
Then we get 142 + 20 + 1 = 163
So n = 163
Lol Thanks!
Start by drawing a Venn diagram (btw I know your in AOPs class because I did it too)
