Would depend on the type of rock not all rock weighs the same. Back when I did tool and die work we had our machinist hand book and it gave weights of various metals and woods I do remember Lime stone was the same as aluminum 168 pounds per cubic foot. Now granite or marble weighs more but use that number and times out your cubic feet and your have a good figure to estimate with.
