Question: how much is 4 quarts of soil?
Answer: Based on my research on potting soil, each quart weights approximately 0.875 pounds; thus, 10 pounds means roughly 11.43 quarts. 10 Quarts equals 9.4 Liters. There are about 25 and 3/4 dry quarts in a cubic foot. A 20 dry quarts package of potting soil is approximately 3/4 of a cubic foot.
