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
66.67 Sq. Yards.
16x18 = 288 sq ft = 288/9 = 32 sq yards.
532.4074 yards of concrete, round up to 533 yards.
4.938 cubic yards.
40 yards.
A yard of concrete is 27 cubic ft. Your measurements, if in feet, represents 480 cubic ft. Dividing this by 27 results in 17.78 yards.
It depends on how deep the concrete. 600 sq ft at 6 inch deep is 300 cu ft = 11.1 yards. 12 inch deep is 22,2 yards; 4 inch deep is 5.5 yards
At a poured depth of 4 inches, you will need 4.94 cubic yards.
A square slab measuring 8 ft by 8 ft by 4 inches will require a minimum of 0.8 cubic yards.
It is about 166.67 cubic feet and you will need just over 6.17 cubic yards of concrete.
You will need a minimum of 39.51 Cubic Yards.
20 feet x 20 ft x .3333 ft = 133.33 cubic feet / 27 cubic feet per yard = 4.94 cubic yards
16 * 20 = 320 sq ft. at 4" thick concrete will cover 80 sq ft. 320 / 80 = 4 yards.
9.3 cubic yards of cement is required for this slab.
