Thus each slab of sod is \[\frac{30}{12} \times 75 = 187.5 \mbox{ square feet.}\] To convert this to square yards I would ask Google. Type 187.5 square feet into square yards into the Google search window. For the weight I again used Google. I entered What is the weight of sod and got some information. Probably the most useful is from Aldino Sod Farms which says that depending on the moisture content sod weighs between 3 and 6 pounds per square foot. I hope this helps,
