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 elevations are two common elevation measurements found on a map key. A contour line represents a specific elevation, while spot elevations indicate exact elevation at a particular point on the map.
Relative location is when a spot is found by using landmarks around the spot. Absolute location is the exact coordinates of the place in question.
An exact spot on Earth is called a geographic coordinate, specified by latitude and longitude. These coordinates pinpoint a precise location on the globe.
Each point on Earth has a unique and unchangeable address due to its latitude and longitude coordinates, which provide a specific location on the planet's surface. These coordinates are based on the Earth's grid system and can pinpoint any place on Earth with a high degree of accuracy.
38 degrees North and 77 degrees West are geographic coordinates that represent a location on Earth. These coordinates pinpoint a spot in the United States, specifically in the state of Virginia.
