Step 1: Use the following as an example.
patio example: 12' x 12' patio with slab 4" thick 12' x 12' = 144 Sq.
Ft. x thickness. -
Step 2: Determine decimal equivalence of thickness
Examples: 6" thick would be .500 4" thick would be .333 3" thick would be .250 Etc. , 12 x 12 = 144 x .333 =
47.952 Sq.
Ft.
This is now converted to Cu.
Yds.
A cube 3' x 3' x 3' is one cubic yard.
Take 3'x 3'x 3' = 27 cubic Ft. per cubic yard. , Ft. / 27 Cu.
Ft. to reach the Cu.
Yards needed. , Yds. , The industry standard is to add 1⁄4 yard (0.2 m). to all material orders.
You do not want to be short on your concrete order.
In this case your initial order amt. would be
1.776 Cu.
Yds. + .250 or 1⁄4 yard (0.2 or
0.2 m). for a grand total of
2.026 Cu.
Yds.
The importance of using all of the decimal points is illustrated in this case scenario.
As you can see the
2.026 Cu.
Yds . in the total amt is not necessary as part of your final order because you have over ordered by 1⁄4 yard (0.2 m).
This will compensate for the
2.026 yards (1.9 m).
Your final order amt. would be
2.0 Cu.

Step 3: This is done based on 1 cubic Ft. 12" x 12" x 12".
-
Step 4: Do the calculations.
-
Step 5: Divide the result 47.952 Sq.
-
Step 6: 47.952 divided by 27 = 1.776 Cu.
-
Step 7: Be sure to use all of the decimal points when doing your math.
