In civil engineering, footings are crucial elements in building foundations. A trapezoidal footing is commonly used when load distribution varies or when columns are located at the edge of the property line. Calculating its volume accurately helps in estimating concrete quantity, material cost, and project planning.

Our Trapezoidal Footing Volume Calculator makes this easy. You just need to input a few dimensions, and the tool will return the required concrete volume in seconds.

Volume Formula for Trapezoidal Footing

The volume of a trapezoidal footing is calculated using the formula:

$\text{Volume} = \frac{1}{2} \times (L_1 + L_2) \times W \times H$

Where:

$L_1$ = Top Length
$L_2$ = Bottom Length
$W$ = Width
$H$ = Depth

Total Volume (if multiple footings)

If you are building multiple identical trapezoidal footings, total volume is:

$\text{Total Volume} = \text{Volume of One Footing} \times \text{Number of Footings}$

Real-World Example

Let’s calculate the volume of a single trapezoidal footing with the following dimensions:

Top Length $L_1 = 1.2 \, \text{m}$
Bottom Length $L_2 = 2.0 \, \text{m}$
Width $W = 1.0 \, \text{m}$
Depth $H=0.5 m$

Step-by-step Calculation:

$\text{Volume} = \frac{1}{2} \times (1.2 + 2.0) \times 1.0 \times 0.5 = 0.8 \, \text{m}^3$
