You should calculate the volume of your slab in cubic yards. First get the volume in cubic feet by multiplying your dimensions together (change 4" to 1/3 ft) . This gives; 80 x 13 x (1/3) = 347 cf (rounded off). Next change to cubic yards by dividing by 27 , since 1 cy = 27 cf. This gives; 347/27 = 13 cy (rounded off). When you buy yards of concrete you are really buying cubic yards and the amount you will need for your slab is 13 yards.
you also can multiply length x width x depth and change you're inches to decimals for example 4" will be .33 so 80 x 13 x.33=343.2 then you divide 343.2 into 27 and you get 12.7 rounded is 13 if your not sure how to convert your inches get a construction calculator
