Concrete Footings - Volume
Estimate required concrete footing volume.
Concrete is in general calculated in cubic yards - cy. Required concrete for footing can be calculated as
v = 0.0031 l w t (1)
where
v = required concrete - cy (cu. yards)
l = length of footing (ft)
w = width of footing (ft)
t = depth of footing (in)
- 1 cy (cubic yard) = 27 cubic feet
- 1 ft = 12 in
Concrete Volume - CY per Linear Foot of Footing

- 1 cy per linear foot (y3/ft) = 2.5 m3/m
