Roughly 22 square yards.
7 feet = 2 yards and 1 foot
depends on the depth that you need to cover the 1200 square feet (area) to. there are 3 foot to 1 yard (1 foot=3 yards). so 1 square foot = 9 square yards (3x3). 1200 square feet = 1200 x9 = 10,800 square yards. you then multiply the 10,800 by the amount of yards (depth) that you want to cover the area to.
the answer is 40 square yards
An 8 foot long table is probably 30" wide. So, you'll need to cover 8 ft + 30 in + 30 in = 13 linear feet. To allow for the gathering you will want to double the length (26 feet) or approximately 9 yards.
That's 18 square feet - which is 2 square yards.
10-ft by 10-ft = 100 square feet = 111/9 square yards.
Broken down as follows: 30 feet = 10 yards 36 feet = 12 yards 10 x 12 = 120 square yards
Well 3 yards are in 1 foot so its 5 yards by 5 yards. So 5yds^2.
As there are 3 yards in 1 foot, 20 yards and 1 foot is 61 feet.
3200 square foot equals how many yards
2.37 cubic yards of stone for every 3 inches deep it needs to be
