If the scale of a map is 1:1000,a 10cm map has an actual length of ?

1:1000

= 10cm : 10000 cm

10000 cm = 100 m

To find the actual length, we need to use the scale ratio.

The scale ratio of 1:1000 means that every 1 unit on the map represents 1000 units in real life. In this case, the units are centimeters.

So, if the map is 10 centimeters long, we can use the scale ratio to find the actual length:

10 cm * 1000 = 10,000 cm

Therefore, a 10 cm map with a scale of 1:1000 has an actual length of 10,000 centimeters.
