A yard is 3 feet, so 12 x 10 = 120, and 120 x 3 = 360. You would need 360 yd2.
Your math is flawed. True, a yard does equal 3 feet but, all you did was multiply the square feet by 3. Your answer of 360 yd2 would equal a room 36 feet x 90 feet.
The true math would be
12 feet = 4 yards.
10 feet = 10/3 yards (3 1/3)
Now multiply the 2 to get 4 x 3 1/3 which equals 13 1/3 yd2
Roughly 22 square yards.
You need 166.66 square yards of carpet.
Broken down as follows: 30 feet = 10 yards 36 feet = 12 yards 10 x 12 = 120 square yards
10 square yards. Note, the amount of carpet you have to pay for may actually be more than 10 square yards as you will have to buy the entire width of the roll * the length you need. Assuming it is 12' wide you would need 12 square yards and if its 15' wide you would need 15 yards. No carpet store sells carpet by what you need but only by what the width of the roll is. So if you need a 10 x 9 piece, the carpet only comes 12 foot wide so you would take home a piece of carpet 12 x 9.
12ft X 32ft = 384 sq ft /9 = 42.67 sq yds

You will need at least 32 square yards of carpet to cover that area.
A 12 by 15 room: 12 x 15 = 180 180 divided by 9 = 20 (one yard is 9 square feet) So, depending on the room, you might need 20 to 21 yards of carpet for a 12 by 15 room. John
To calculate how many square yards of carpet you need use this formula.width X length= total square footage/9 = number of yardsSo you will need 16 square yards of carpet.
You will need a minimum of 38.6 square yards of carpet to cover that area.
55.56 yards of carpeting. Just divide the feet by 9 and that gives you the yards. --------------------------------------------------------------------------------------------------------- The above will give you square yards of floor, but you need to know what size the roll of carpet is. Example, if the carpet comes on a 12 foot roll and the room is 10 by 20 (200 sq ft or 22.22 sq yrd) but you would have to buy 12 by 20 (240 sq ft or 26.66 sq yrd). You need to determine the size of each piece of carpet and then figure your squre feet /9.
