# Trapezoidal Footing Calculator | Trapezoidal Formula | Volume of Trapezoidal Footing Important Point

## How To Work With Trapezoidal Footing Calculator?

In this calculator, we calculate the trapezoidal footing area. As per the below process work with calculator.

Step – 1.

Fill Footing area Length and Breadth as per below picture shown. In this footing Bottom (base) area and Top area are different so carefully check in above image. Here, As per the below image Bottom area Length A and Breadth B Fill in box And As per the below image Top area Length a and Breadth b Fill in box Step – 2.

Fill Footing area Height in box as per shown in below picture In this footing Bottom (base) height and Top height are different so carefully check in above image. Here, As per the below picture shown fill Footing Bottom(Base) Height H1 in box. As per the below picture shown fill Footing Top Height H2 in box. Step – 3. ## What is a Trapezoidal Formula?

Volume of Trapezoidal =

h/3 * ( A1 + A2 + √ (A1 x A2 )) Here,

A1 (Bottom area of Trapezoidal) = Length A * Breadth B

A2 (Top area of Trapezoidal) = Length a * Breadth b

h Height of Trapezoidal = H ## How to Find Volume of Trapezoidal Footing?

Trapezoidal Footing Formula = F1 Area + F2 Area F1 Area = Length A * Breadth B * Height H1

F2 Area = H2/3 * ( A1 + A2 + √ (A1 * A2 ))

A1 (Bottom area of Trapezoidal) = Length A * Breadth B

A2 (Top area of Trapezoidal) = Length a * Breadth b

Here,

F1 = Base Footing area

F2 = Traprzoidal Area of Footing

Length A = Bottom Footing Length of X-direction.

Length B = Bottom Footing Length of Y-direction.

Length a = Top Footing Length of X-direction.

Length b = Top Footing Length of  Y-direction.

H1 = Height of Bottom Footing.

H2 = Height of Terpziodal Footing.
