Why would a scale map look like 1:24000 (10') I don't know what that 10 means

It means 10 ft.

So would that be a fraction of the map of ft depth per square inch

Sorry for the late reply!

Not 100% sure but I believe so.

If I am wrong, please do post back and tell me the right answer ( but I hope we're both right =) )

In a scale map, such as 1:24000, the first number represents the map distance, and the second number represents the real-world distance. In this case, 1 unit on the map represents 24,000 units in real life.

Regarding the "10" in parentheses, it is common for scale maps to include a representative fraction along with an equivalent graphic scale. The number in parentheses can be the abbreviation of a unit, like "10' " which stands for 10 feet. This means that one unit on the map represents 10 feet in actual distance.

So, in the given example, every unit of length on the map represents 10 feet in real life when measured on the ground. This allows you to understand the actual distance by simply multiplying the measurement on the map by 10.
