Envelopes come in dozens of sizes, designed to hold various sizes of paper, stacked or folded in various ways.
I have 6 sealed envelopes on my desk, whose sizes are listed here:
| |
4.125" x 9.5" |
Business envelope |
| |
3.5" x 9.25" |
Chou 30 envelope (from Japan) |
| |
4" x 5.5" |
Greeting card envelope |
| |
9" x 12" |
Large manila envelope |
| |
7.5" x 10.5" |
Small manila envelope |
| |
9.125" x 9.125" |
Square envelope |
Each envelope has a single digit written on the outside of it. Some of the envelopes are inside of others; there's even one envelope that's inside an envelope that's inside another one. All of the envelopes are lying flat; I haven't folded, cut, rolled, wrinkled, or otherwise modified them to make them fit.
To find this cache, you'll need to figure out what number is written on each envelope, from the clues below:
| |
Exactly four of the envelopes are inside of other envelopes. One of the two "outside" envelopes has a transparent window, through which the number 7 is visible. Except for that window, the envelopes are opaque. |
| |
The number on the greeting card envelope equals the number on one of the other envelopes; there are no other duplicate numbers. |
| |
The product of the 6 numbers is 20160. |
| |
The number on the square envelope equals the number of envelopes inside it. |
| |
The number on the Chou 30 envelope is the sum of two of the other numbers. |
| |
The number on the large manila envelope equals the average of the numbers on the envelopes inside it. |
Once you've figured out what's written on each envelope, go to the coordinates below:
| |
N 40 51. (Chou 30) (small manila) (large manila) |
| |
W 124 09. (greeting card) (square) (business) |
If you think you've figured out the coordinates, you can check them with certitude:

The cache is a camouflaged match holder, located in the Ma-le'l Dunes north of Manila. There's a small pencil in the cache, but you should probably bring your own, just in case.
NOTE: A sign at the parking area says "Day use only: Gate opens at sunrise and closes 1 hour after sunset.".
