A normal pallet of sod covers 500 square feet
70 square yards
From the info I have from a sod supplier: each roll is 10sqft, there are 70 rolls on a pallet, so covers 700sqft
To cover 192 square feet, you need 192 square feet of covering. If you happen to buy it in 4' x 8' pieces, then exactly six pieces do the job.
You are going to need 4 bundles. 3 bundles equals a square and a square equals 100 square feet.
Walmart offers a carton with 5 pieces of granite tile at 3/8" thick and 12" wide X 12" long for $80.00. Each package has a shipping weight of 27.5 pounds. One pallet contains 66 cartons! That's about $4900.00/pallet load, to cover 330 square feet. I dare you to ask for free shipping!
The answer is 12,000 leafs
One piece = 4 x 12 = 48 square feet 665 pieces cover (665 x 48) = 31,920 square feet 3,5462/3 square yards 0.001145 square mile (rounded).
A 30 foot circle covers about 707 square feet. 23 pieces would technically cover that. I'd get 30 of them so I wouldn't have to cut any of them.
One square covers 100 square feet, with 3 bundles per square equals 51 bundles.
There are 1/0.048906 = 20.45 So 20 pieces is not enough to cover 1 sq metre while 21 is. Alternatively. 20 pieces can fit in 1 sq metre but 21 will be too many.
