How do I calculate how much concrete I need for a roof slab?
- The volume of Concrete = Area of rectangle x Depth.
- The volume of concrete = Surface Area x Depth.
- The volume of concrete for circular column = Surface Area of Circle x height of the column.
- Part1: It is in a rectangular shape with the following dimensions length=1.0m, breadth=0.8m and depth=0.4.
- Part 2:-
How do you calculate concrete for a roof?
Cement required for 100 sq ft roof slab 4 inch thick Wet volume of concrete is equal to 100 sq ft × 0.334 ft = 33.4 cu ft. For converting wet volume of concrete into dry volume of concrete we will multiply 1.54 into wet volume of concrete.

Example calculation Estimate the quantity of cement, sand and stone aggregate required for 1 cubic meter of 1:2:4 concrete mix. Ans. Materials required are 7 nos. of 50 kg bag of cement, 0.42 m 3 of sand and 0.83 m 3 of stone aggregate.
How to calculate the amount of concrete you need for your project?
1 Mark your area that needs concrete and divide it into smaller areas. 2 Calculate the volume of your area after determining its shape (see the examples below) by multiplying it with the thickness of the concrete. 3 Convert the volume from feet to cubic yards to get a precise number of concrete that you need – in cubic yards.
