How many square ft in a yard of crushed rock? - Answers

The question as stated makes no sense, as square feet is a measure of area and "yard", is a measurement of volume. Normally, "yard" is a measurement of length. However, concrete, soil, gravel, sand, etc., are normally sold (in the U.S.) by the "yard" which is simply short for "cubic yard." However, you may easily calculate the area that a yard of crushed rock will cover, depending on the desired depth of crushed rock. As a cubic yard is 3 feet by 3 feet by 3 feet, which is equivalent to 9 square feet by 36 inches, simply divide 36 inches by the desired depth in inches, and multiply it by 9 square feet. Thus, if you wanted a depth of 8 inches, 36 divided by 8 is 4.5. So, you can cover 4.5 square yards, or 4.5 times 9 square feet = 40.5 square feet, which would be a square area approximately 6 feet 4 inches by 6 feet 4 inches.
