# 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
