What is a Trapezoidal Formula?
Volume
of Trapezoidal = h/3 x (A1 + A2 + √ (A1 x A2))
where,
Height of Trapezoidal h = “H”
The bottom area of Trapezoidal A1 =
Length “A” x Breadth “B”
The top area of Trapezoidal A2 =
Length “a” x Breadth “b”
“Refer
the diagram below diagram”
How to Find Volume of Trapezoidal Footing
concrete?
Volume of Trapezoidal Footing Formula = F1 volume+ F2
volume
Where,
F1 = Base
Footing area | F2 = Trapezoidal
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 Trapezoidal Footing.
F1 volume = Length “A” x Breadth “B”
x Height H1
F1 volume =
1.2m x 1.2m x 0.300m = 0.432 cum
F2 volume = H2/3 x (A1
+ A2 + √ (A1 x A2))
A1
(Bottom area of Trapezoidal) = Length “A” x Breadth “B”
A1
(Bottom area of Trapezoidal) = 1.2 x 1.2 = 1.44 sqm
A2
(Top area of Trapezoidal) = Length “a” x Breadth “b”
A2
(Top area of Trapezoidal) = 0.6 x 0.6 = 0.36 sqm
F2 volume =
0.3/3 x (1.44 + 0.36 + √(1.44 x 0.36))
F2 volume = 0.1
x (1.44 + 0.36 + 0.72) = 0.252 cum
Volume of Trapezoidal Footing
Formula = 0.432 + 0.252 = 0.684 cum
