You can calculate the required volume of gravel by multiplying the gravel path area by the desired thickness: 23 yd² * 0.1 yd = 2.3 yd³. The last things to assess are the estimated weight of the required gravel and its cost. Knowledge about the weight of the cargo may come in handy when it comes to transportation.
