Concrete Slabs - Volume Estimates
Estimate required concrete volume per sq. ft.
Required concrete is in general calculated in cubic yards (cy).
v = 0.0031 l w t (1)
where
v = required concrete - (cy, cu. yards)
l = slab length (ft)
w = slab width (ft)
t = slab depth (in)
- 1 cubic yard = 27 cubic feet
- 1 ft = 12 in
Slab Concrete Volume
| Depth (in) | Volume (cy/sq.ft.) |
|---|---|
| 2 | 0.006 |
| 4 | 0.012 |
| 6 | 0.019 |
| 8 | 0.024 |
| 10 | 0.031 |
- 1 in (inch) = 25.4 mm = 2.54 cm = 0.0254 m
- 1 yd3 = 0.7646 m3
- 1 ft2 = 0.0929 m2
Area Covered by Concrete
The table below shows the area (sq.ft.) that 1 cu. yard of concrete will cover for various depths.
| Depth (in) | Area (sq.ft.) |
|---|---|
| 2 | 162 |
| 3 | 108 |
| 4 | 81 |
| 5 | 65 |
| 6 | 54 |
| 7 | 46.3 |
| 8 | 40.5 |
| 9 | 36 |
| 10 | 32.4 |
| 11 | 29.5 |
