Measure the length, height and width (depth) of the rock.
Determine the specific gravity of the rock (if you know what type of rock you're measuring, refer to the chart on the EduMine website for specific gravities of various rock types).
Multiply the volume of the rock by its specific gravity.

How do you estimate the weight of a large rock?

The average weight of a sandstone boulder is approximately 150 pounds per cubic foot. Limestone boulders and granite boulders in most cases weigh more. They average about 175 pounds per cubic foot. To estimate the quantity, you need to convert the area into cubic feet by multiplying length x width x height.

How many boulders are in a ton?

per cubic foot = 24,000 lbs. There is 2000 lbs in one ton so you would need 12 tons of boulders to build that substantial wall.
