Answer 1

Odd dimensions for a pool table... Check your measurements.  Follow the below calculations if you change your numbers.  

Slate is obviously quite heavy, it's density is 2691 kg/cu. m

12 feet x 12 feet x 1 inch = 12 cubic feet

12 cubic feet = 0.339802159 cubic meters

(0.339802159 cubic meters) x 2691 kg/cu. m = 914.40761 kg

914.40761 kg = ...

...2,016 pounds.
