how much does a 6-10in rock feildstone weigh. I ahve a job tomorrow that requires 150 feildstone, I big it today and got the job. I just bid it real high because I was sure how much they weigh... But anyway, they charge .11 per pound... I just figured each rock would cost $2 max, so I figured that in + my time. Im hoping it'll be like .60 per rock max. but atleast im covered now incase they are like 18lbs but a 8" rock weighing 18lbs is unreal. lol. I would call the store, but they closed at 5. and i dont want to wait until tomorrow to find the answer. lol. Thanks guys! again its Michigan Fieldstone.
