at 9 sqft per sqyd, you need 188/9 = 21 sq yds, commonly called a yard in the carpet business
39 yards x 100 yards = 35100 sqft (I do not know what lyds are!)
Square feet x 0.111 = square yards
31' x 14' = 434 sqft 434 / 3 / 3 = 48.22 square yards
360 x 159 ie 57240 sqft
80.0 Sqft
79.7778 square yards (0.111111 square yards per square foot).
200 square yards is 1,800 square feet.
39 yards x 100 yards = 35100 sqft (I do not know what lyds are!)
Square feet x 0.111 = square yards
31' x 14' = 434 sqft 434 / 3 / 3 = 48.22 square yards
Base it off : 12" thick a yard of concrete will go 27sqft. 6" thick will go twice as many sqft so 54 sqft. 4" thick will go 3 times as many sqft so 81 sqft 2" thick will go 6 times as many sqft so 162 sqft and at 1" thick it will go 324 sqft. So at 5" thick...1 yard of concrete will go 67.5 sqft
Five--a roll will cover 400 square feet of area.
A yard is a unit of length. A square foot is a unit of area. The two units are therefore incompatible.
4840 sq yards = 43560 sq feet
360 x 159 ie 57240 sqft
It depends on how many square feet the box will cover. I found two different brands: one covered 22.93 sqft, the other 17.59 sqft. your room is 12' x 14' = 168 sq.ft so 168 sqft / (22.93 sqft / box) = 7.32 boxes for my first example and 168 sqft / (17.59 sqft / box) = 9.55 boxes for my 2nd example Hope this helps
A square of shingles is 100 sqft. there are 3 bundles in a square. 1267 sqft is better rounded off to 1300 sqft to allow for waste. so 13oosqft dived by 100 sqft = 13 squares. 13 x 3 = 39 bundles.
