In an earlier post, we have discussed how to calculate the material for concrete? & now we are going to see how to calculate the volume for trapezoidal footing volume along with an example.
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
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

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???
