    The volume of a rectangle is zero. Volume = L X W x H = 18 x 4 x 0 = 0

    You need the thickness of the cement in yards and your answer will be in cubic yards.
    Cement is sold by the cubic yard. Cement might be 4-6" thick. 6" = .166 yards. At 6" thick you would need 11.952 cubic yards of cement.
