Individual Footings Are Mostly Used In
Residential Buildings And Small Building. Usually Individual Footing Have The
Shape Of Rectangular, Square And Trapezoidal.

Rectangular And Square Shape Footings Are
Calculated The Volume By Simple Steps

Volume Of Rectangular Footing = Area ( A x
B ) X Height

Volume Of Square Footing = Area ( A

^{2}) X Height
Also Trapezoidal Footing Volume Calculation
is The Easy Process. I Will Explain Broadly About Volume Calculation Of
Trapezoidal Footing Below.

V = H / 3 ( A

_{1 }+ A_{2 }+ √( A_{1}X A_{2 })
H = Height Of Trapezoidal Portion

A

_{1 }= Area Of Bottom Of Trapezoidal Portion
A

_{2 }= Area Of Top Trapezoidal Portion
Example Calculation For Trapezoidal Footing
Volume Calculation.

V = H / 3 ( A

_{1 }+ A_{2 }+ √( A_{1}X A_{2 })
Where H= 0.3 M

A

_{1}= 1.5 X 1.5 = 2.25 M^{2}
A

_{2}= 0.9 X 0.9 = 0.81 M^{2}
V = 0.3/ 3 ( 2.25+ 0.81+ √( 2.25 X 0.81

_{ })
V = 0.1 ( 3.06+ 1.35)

V = 0.441 M
