How many sq ft In 4 yards of concrete 4in deep?

To calculate the square footage covered by 4 yards of concrete at a depth of 4 inches, first convert the depth to feet (4 inches = 4/12 = 1/3 feet). Then, calculate the volume in cubic feet: 4 yards is 4 x 27 = 108 cubic feet. Finally, divide the volume by the depth: 108 cubic feet / (1/3 feet) = 324 square feet. Therefore, 4 yards of concrete at 4 inches deep covers 324 square feet.
