Calculation Cement , sand and Aggregate of Trapezoidal Area

 M20= 1:1.5:3

Volume of trapezoidal footing Trapezoidal = Cuboid + Truncated pyramid



1. Rectangular (Cuboid)= LxBxH



2. Truncated Pyramid = 1/3 (A1 + 𝐴2 + √𝐴1𝐴2) H



Where 

  • A1 = Area of Top base
  • A2 = Area of Bottom Base
  • H = Height
