To determine the amount of stone needed for a 1,200 square foot foundation, you'll first need to know the desired thickness of the stone layer. For example, if you plan to use a 6-inch thick layer of stones, you would calculate the volume by multiplying the area (1,200 sq ft) by the thickness (0.5 ft), resulting in 600 cubic feet of stone. Considering that a cubic yard contains 27 cubic feet, you would need about 22.2 cubic yards of stone. Always consult with a local contractor for specific requirements and adjustments based on your project's needs.
