Final answer:
To provide 6-digit grid coordinates for points A, B, and C on a map, clarification is needed on whether to use a grid reference system or latitude and longitude.
Step-by-step explanation:
To determine the 6-digit grid coordinates for points A, B, and C on a map, one would typically use a system such as the Universal Transverse Mercator (UTM) coordinate system or a similar grid reference system. The question, however, specifies the use of the NASA Latitude and Longitude Finder to determine the latitudinal and longitudinal coordinates for each location. It is important to recognize that these are different systems of location reference. Latitude and longitude provide a geocode for locations on the Earth's surface in degrees, while grid coordinates are a flat projection used in specific mapping systems, often providing a string of numbers to represent a location on a grid-based map.
To answer your question accurately, I would first need the map that you are using to acquire the exact locations for points A, B, and C. Once I have the map, I would locate each point and read the latitude and longitude directly from the map or use the NASA Latitude and Longitude Finder to obtain these values. Since the question seems to be a mix-up between coordinate systems—asking for grid coordinates but directing to use a latitude and longitude tool—it would be best to clarify the requirement before proceeding.
