how much do boulders weigh
If you are looking for a boulder for the flower bed, measure the length, width and height of your ideal stone. Roughly calculate that into cubic feet. For example if your measurements are 2 ft. long by 2 ft. wide by 18â³ high â 2 x 2 x 1.5 = 6 Cubic Feet. Dense stone usually weigh approximately 150 per cubic foot. Multiply our 6 C.F by 150 lbs. = 900lbs Our most expensive cathedral boulders run up to .20 per lb. but our locally grown boulders run .13 per lb. Cathedral Boulder.20 x 900lbs = $180. Limestone or Sandstone.13 x 900lbs = $117. This is where our scales come into play.
