a cubic yard of sand is spread uniformly to completely cover a rectangular path that is 3 feet wide and 24 feet long. how many inches deep is the sand that covers this path? express your answer as a mixed number
The sand is 3 feet wide and 24 feet long, so the total area of the path is 72 square feet. A cubic yard is 27 cubic feet, so the sand is spread over 27/72 = 0.375 feet deep. This is equal to 4.5 inches deep. The answer is 4 1/2 inches deep.
