volume of trapezium = 1/2* (a1+a2)*h* length
where a1,a2 are the base areas respectively
and h is the height
its a good formula but here is a easier one
1/2*(Area of top + Area of bottom)*Height*lenght

The area of a trapezium is given by 0.5*(a+b)*h where a and b are the lengths of the parallel sides and h is the vertical distance between them. The fact that the trapezium is isosceles does not matter. A trapezium is a 2 dimensional object and so it has no volume.
area of trapezium=1/2{a+b}h
the formula for the AREA of a trapeziem is 1/2(a+b)h a=top side b=bottom side h=height its a good formula but heres a easier one 1/2*(Area of top + Area of bottom)*Height
1/2 h(a+b)
volume = length*height*width Rearrange the formula: length = volume/height*width
