Well, and tea, too. But that would have ruined the alliteration.
Anyway, after tea, they decided to burrow out a larger burrow. In the first hour, they burrowed out 427 cubic inches of dirt. In the next hour, they burrowed out 256 cubic inches of dirt. In the third hour, they burrowed out 312 cubic inches of dirt. In the fourth hour, they burrowed out 546 cubic inches of dirt. In the fifth hour, they burrowed out 656 cubic inches of dirt. And in the sixth hour, they burrowed out 823 cubic inches of dirt. They continued for one more hour after that.
How many cubic inches, total, did they burrow in those seven hours?

Here are the sequence of numbers:
427 256 312 546 656 823
If you space it like this you get:
4 27 256 3125 46656 823???
2^2 = 4
3^3 = 27
4^4 = 256
5^5 = 3125
6^6 = 46656
7^7 = 823543
So, in the seventh hour they must have burrowed 543 cubic inches, making the sum 3563.

3563 cubic inches
The numbers 427, 256, 312, 546, 656, 823 can be rearranged as 4, 27, 256, 3125, 46656, 823--- which is 2^2, 3^3, 4^4, 5^5, 6^6, and 7^7, so the last number is 823543

well, "in" from the "How many cubic inches, total, did they burrow in those seven hours?" was referring to the seven hours not the amount of cubic inches burrowed out..

I believe you just average that out and add it to the total. Don't know if they want a decimal though. Good luck on that.

Please stop trying to cheat at the Lenny Conundrum, if you don't get it, wait for an easy one and answer quickly for a trophy and avvie. Leave the prizes for the people who can figure them out fairly please. So please just don't cheat, it lowers the prize pool for the people who solved it fairly.
If you see a question with the name Lenny in it just don't answer it, it's cheating, or you can answer then with something like what I have above, please let the people who solve it fairly, reek the benefits, Thank You.
