In this post, we are going to learn, How To Calculate Volume of Trapezoidal Footing at Construction Site.

To Calculate the Volume of Trapezoidal Footing, We need to calculate two things first. First is the Volume of Rectangular Cuboid and the Second is Volume of Truncated Pyramid. So we can say

Trapezoidal Footing = Rectangular Cuboid + Truncated Pyramid

The formula for Volume of Rectangular Cuboid = L x B x H

Where, L = Length of Cube ; B = Breadth of Cube ; H = Height of Cube

Formula for Volume of Truncated Pyramid = ((A1 + A2 + √A1 x A2) x h) / 3

Where, A1 = Area of Top Base ; A2 = Area of Bottom Base ; h = Height

VOLUME OF TRAPEZOIDAL FOOTING


VOLUME OF TRAPEZOIDAL FOOTING
Volume of Rectangular Cuboid = L x B x H
         = 2 x 1.5 x 0.3 = 0.9 m³
How To Calculate Volume of Trapezoidal Footing
Volume of Truncated Pyramid = ((A1 + A2 + √A1 x A2) x h) / 3
        = ((0.2 + 3 + √0.2 x 3) x 0.3) / 3
        = 0.397 m³
[Note : A1 = 0.4 x 0.5 = 0.2 ; A2 = 1.5 x 2 = 3]
How To Calculate Volume of Trapezoidal Footing
Volume of Trapezoidal Footing = 0.9 + 0.397 = 1.297 m³
