Answer / kumar biswajit sinha

i think the dimension what ever is given in the question is not full , because the formula is =
V = [L X B X d] + h / 3 [ A1 + A2 + ROUTE UNDER A1 A2 ]

where ,
l = length , b = breadth , d = bottom depth , h = D - d ,
A1 = bottom area , A2= top area .

so , how can we calculate ,[ A2 ] top area without dimension .

Answer / rakesh suthar

h/3(area of bottom + area of top+ under root area of
bottom * area of top)

Answer / santosh

volume of trapezoidal footing = H/3{a1+a2+square root a1.a2}
here a1 = area in bottom of footing
a2 = area in top of footing
H = height of footing

Answer / sathy

Concrete quantity = H/3 [ a2 + b2 + square root of a2 x b2]

H = height of the trapezoidal footing

a2 = Area of the bottom of footing

b2 = Area of the top of footing

Answer / s.kumar

Volume of Trapezoidal footing= h/2(a+b)*l
where,
h= depth of footing
a= top width of footing
b= bottom with of footing
l= length of footing
In Case of Frustrum of Pyramid
V= h/3(A1+A2+Square root of A1*A2)
Where,
A1= Area of top section (a*b)
A2= Area of Bottom Section (A*B)

Answer / abid

h/6(a1+a2+4a m),
a1= area of top
a2= area of bottam
am=average of both area
h= height at mid (like:-D)

Answer / kuldeep yadav

V2= D/6(a1+a2+4Am)where Am=(a1+a2)/2
And D=D-d(total Depth-rectangular Depth)
a1=area Of Footing Bottom
a2=area Of Footting Top

V1=(LxBxd)
V=V1+V2

Answer / abiy

from trapezod forula of area a=h/2*(b1+b2)
a=2/2*(1.7+0.5)=2.2m2
from volume formula v=a*d=2.2*0.15=0.33m3

Answer / uday dudhrejiya

[L.b.d(small depth)] + h/3 {A1+A2+√(A1.A2)

Answer / manimaran.r.

V=1/2*√((a1^2+a2^2))*d
where
a1=area of bottom
a2=area of top
d=d1+d2
