4.5 yards (for a 4" deep pad) make it 5 even yards to be 'safe'
6.7 yards (for a 6" deep pad) make it 7 even yards to be 'safe'.
Formula: (20 * 18 * 0.33) divided by 27
(There are 3*3*3 = 27 cubic feet in 1 cubic yard)
.

I think 120.
20x18 is 360,and 360 divided by 3 is 120.

voume = Length X Width X Height
Thats 6.7 yd(20ft) X 6 yd(18ft) X however deep you want it (in yards)
