1 sq. feet = 144 sq. inches
So,
392 sq. feet = 144 * 392 sq inches = 56448 sq. inches
Volume of cement needed = 56448 sq inches * 4 inch = 225792 cubic inches
225792 cubic inches = 1568 cubic feet

depends how deep
13*13*6=1014 yards of cement
26 square feet.
Convert the 4 inches into feet first. 4/12 = .33 feet. Now, compute the volume by multiplying the area of 64 square feet by .33 feet, and you get 21.12 cubic feet. Sometimes cement is ordered by the yard (cubic yard) and since there are 27 cubic feet in one cubic yard, you would divide 21.12 by 27 and get .78 yards.
well do to my calculations i made is that it is 6 or 18 feet long
