We would need to see the map used for that question to determine the grid coordinates. Locate the hill on the map marked as 192. Now look to the left for the first grid line you come to. Mentally divide the grid square into 100 lines, and approximate or measure to the right. If the grid line is 47, and hill 192 is in the middle between grid line 47 and 48, the coordinate would be 750.
Now do the same with the elevation line below hill 193. Measure the 1/100th level up from that line to the next. If the line is 14, and it is half way up, it would be 450. The entire 6-digit coordinate in that example would be 750450.
Contour lines and spot elevation labels.
A contour line or a spot height.
Any particular geographical spot on the earth can be located by its longitude and latitude coordinates.
At our school, we are given drill cards and it tells us where we're located on the grid system and learn it spot by spot.
There are not exact coordinates as the hot spot covers a large area. However, it appears to be centered under the eastern part of the Big Island, so a decent approximation would be 19.3° N 155.3° W

The Pocono Mountains are located in Pennsylvania. It is a popular tourist attraction and vacation spot for many. Its elevation is 2693 feet or 821 meters.
