# How To Calculate Trapezoidal Footing Volume

In an earlier post, we have discussed how to calculate the material for concrete & now we are going to see how to calculate the volume for trapezoidal footing volume along with an example.

## Trapezoidal Volume Calculation Formula

The below formula has used for calculating the volume of the trapezoidal footing.

V = H/3 (A1+A2+(√A1 x A2)

A1 = Area of Lower Portion

A2 = Area of Upper Portion

H = Height of trapezoidal portion

Let us see an example.

Refer below the Diagram. Now we are going to calculate the volume of the trapezoidal footing.

Volume =  H/3 (A1+A2+(√A1 x A2)

A1 = 2 x 1.5 = 3 Sqm

A2 = 0.5 x 0.3 = 0.15 Sqm

H = 0.15m

Now Volume = 0.15/3 x (3+0.15+(√3 x 0.15)

=  0.05 x (3.15+0.67)

= 0.19 Cum

Volume (V) = 0.19 Cum
