If a drain pipe is 28 feet long, calculate the total drop with a slope of 1/8 inch per foot.

Explanation:
Total drop comes from multiplying how far the pipe runs by how much it drops per foot. With a slope of 1/8 inch per foot, the pipe drops 0.125 inch each foot. Over 28 feet, that’s 28 × 0.125 = 3.5 inches, which is the same as 3 1/2 inches. So the total drop is 3 1/2 inches.
