Creeping phlox makes a great groundcover. The number of plants you will need depends upon how quickly you want an area to fill in. an individual plant can be expected to cover an area 9-12 inches across in a good season. If you are in a hurry and want it to fill in quickly, plant them 9 inches on center (from the center of one plant to the center of another). That means you would need 175 plants to cover 100 square feet of ground. But if you are patient and willing to wait, you can plant them 18 inches on center and you will only need 45-50 plants to cover the area. In your 10 by 30 foot space (300 square feet), you will need anywhere from 150 to 425 plants, depending upon spacing.
