Trapezoidal Volume Calculation Formula
The below formula is used to calculate 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
Example Footing Calculation
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 m3
Volume (V) = 0.19 m3

Very good page for learning and growing
Please share derivation of the above formula. (Trapezoidal footing)
Very good web site
Height or slant height ?
Bottom cuboid volume is not considered in ready calculator???
