3.0107 cubic meters
You will need 0.56 cubic yards of concrete.
This is a volume of 3.33 cubic meters.
96 cubic feet of concrete
It is about 166.67 cubic feet and you will need just over 6.17 cubic yards of concrete.
A cubic foot is 12" thick 12" wide and 12" deep. .45 cubic feet per 60# bag of concrete
A 28 meter square is 28 times 28 meters or 784 square meters. If it is one tenth of a meter (10 cm) deep, it has a volume of 78.4 cubic metersIf you mean 28 square meters (like a pool 4 meters by 7 meters) then the volume one tenth of a meter deep is 2.8 cubic meters.
If it is 4 inches deep/thick, 2 cubic yards. If it is 6 inches deep/thick, 3 cubic 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.
You need 1.35 cubic meters for each centimeter deep.
A Yard of Concrete? what unit is this? Linear? Cubic? Front yard or back? I suppose it is a Cubic Yard of Concrete. The answer is (36/3)*9 = 108sf
