First you need know how much(in volume) the bag makes. Lets say a bag makes L cubic feet. where L is a whole number.
2 inches =1/6 ft
volume of patio (assuming its a rectangular prism) is 10x16x(1/6) = 80/3
number of bags = (80/3)/L = 80/3L.
* If this number isn't a whole number, round to the next whole number.
