                        12.5 centimeters

7. What is the contour interval on your map?

            20 feet

8. What are the approximate geographic coordinates for:

a) The Public Affairs Building

            Degrees/Minutes/Seconds: N 34° 04’ 26’’ / W 118° 26’ 23’’

            Decimal Degrees: 34.0739 N, 118.4397 W
