Density value is missing!!!!!!
It depends on the density of the cement. You wont get an accurate answer without the details.
.936 cubic feet
1.85 cubic yards of cement.
27 cu ft
20 x 24 x 1 = 480 cubic feet
A cubic foot is a unit of volume. A kilogram is a unit of mass. The two units are therefore incompatible.
5.93 cubic yards.
147 cubic feet of cement are required.
It would depend on how big the bag of cement is. 1 foot bags will be more in the cubic meter than 2 feet.
A typical cement truck can hold between 10 to 12 cubic yards of concrete, which is equivalent to around 270 to 324 cubic feet.
60 x 40 x .05 = 1200 cubic feet, divided by 27 (as there are 27 cubic feet in a cubic yard) answer 44.44 cubic yards
