Question 10609
assuming you have a regular shape, then:


volume = (cross-sectional area)*(length)


so, for your trapezium, its volume is given by area*length.


area of trapezium = (h/2)(a+b), where a and b are the 2 parallel sides and h is the perpendicular distance between them.


so vol = (h/2)(a+b)*length
