Assuming you use the standard 4" depth, you will need at least 1.75 cubic yards.
Two squares.

9ft x 9ft, or 81ft2 is the same as 24.6888 meters2.
20ft X 14ft = 280 sq ft /9 = 31.11sq yds X $3.00 = $93.33
3ft = 1yd => 9ft = 3yd So a room 9ft x 9ft = 3yd x 3yd = 9 sq yd.
Total square yards: 21.78
14ft x 12ft = 168 sq ft = 15.6 m2
A 30ft x 14ft room = 420 square feet.
14*14 = 196 square feet
1 cubic foot = 7.48052 gallons (rounded)50yd x 50yd x 9ft = 150ft x 150ft x 9ft = 202,500 cubic ft = 1,514,805 gallons (rounded)
81 square feet (9 x 9 = 81).
The actual measurement usually given is 9ft by 4.5ft, as there is nothing associated with pool and billiards that is referred to as 9ft x 5ft. And even the 9ft x 4.5ft isn't correct. A 9 foot pool table, described as 9ftx4.5ft, has outside dimensions of about 112 inches by 62 inches. This is actually very close to the 9ft x 5ft that was asked about.
