So, you’re wondering what’s the math behind that calculation?
50′ x 12′ x 13′ = 7,800 cubic feet
FYI, Slate = 168 lbs per cubic foot
7,800 cu ft x 168 lbs = 1,310,400 lbs of stone!
Maybe you are wondering, how many squares of roofing slate does 650 tons of stone yield? Great question! Send us your guesstimate and I will send you a New England Slate “I’d Nail That” t-shirt! firstname.lastname@example.org
