16 * 20 = 320 sq ft. at 4" thick concrete will cover 80 sq ft.
320 / 80 = 4 yards.
How many square yards in a 20x18 feet 3 inches thick
about 26.4 is the volume i think.......
Assuming 4 inches thick, about 65.19 yards or rounded 66 yards (always round up to nearest yard).
6 inches is 1/6 of a yard, so a cubic yard of concrete will cover 6 sq yards = 54 sq ft
one (1) cubic yard of concrete four inches thick will cover 80 sq. feet. 85 yards x 81 = 6885 sq. feet.
39.1116 cubic yards
1000 square feet/9 = 111.1 square yards of concrete 6 inches thick. This is the same as 111.1/4.5 = 24.7 cubic yards of concrete.
How many square yards in a 20x18 feet 3 inches thick
It should be a little over 19 yards.
One square yard is nine square feet, so 27 square feet is equivalent to 3 square yards. So 3 yards of concrete will cover 27 square feet.
about 26.4 is the volume i think.......
10 yards
Assuming 4 inches thick, about 65.19 yards or rounded 66 yards (always round up to nearest yard).
To my knowledge, concrete is measured in cubic yards. you would convert your measurements to yards 2000 sq ft is about 222.22 sq yards 4 inches is about 0.11 yards multiply to get volume, about 24.7 cu yards
6.67 Cubic Yards
A 9x9 foot slab 4 inches thick requires a minimum of 1 cubic yard. If you go to 6 inches thick you will need 1.5 cubic yards.
A square slab measuring 8 ft by 8 ft by 4 inches will require a minimum of 0.8 cubic yards.
