To convert the area from square feet to cubic yards, you need to consider the thickness of the concrete.
Given:
Area of the patio = 200 ft^2
To convert the area from square feet to cubic yards, you need to multiply it by the thickness of the concrete. Let's assume the thickness is t feet.
So, the volume of the concrete needed will be:
Volume = area * thickness
Volume = 200 ft^2 * t ft
To convert the volume from cubic feet to cubic yards, you need to divide it by 27 (since there are 27 cubic feet in one cubic yard).
Now let's calculate the volume of concrete needed in cubic yards:
Volume in cubic yards = (200 ft^2 * t ft) / 27
Since we don't have the thickness value (t), we cannot directly calculate the volume in cubic yards. Please provide the thickness in feet, and I can help you with the calculation.
