How much dirt does it take to cover 6 feet by 6 feet 6 inches deep?

To calculate the amount of dirt needed to cover a space that is 6 feet by 6 feet and 6 inches deep, we first convert all measurements to feet. The depth of 6 inches is 0.5 feet, making the total volume (6 \times 6 \times 0.5 = 18) cubic feet. Therefore, it takes 18 cubic feet of dirt to cover that area to the specified depth.
