Doing a silly maths course for work and have managed to work out the surface area but am unable to work out the volume...
It wont work if you just multiply the surface area x height

I'm pretty sure it's the average of the base areas times the height of the object.
So find the area of the parallel bases, add them and divide by two. Then use the height of the trapezium (remember that the height has to form a right angle with the bases) and multiply by the average of the base areas.
Hope this helps. Good luck.

The definition of a trapezium is a quadrilateral with no parallel sides. If you are finding the volume of a trapezium, you can't find it because trapezium is just a two-dimensional figure. But if you are going to find the area of a trapezium,
1. base X height or
2. try to form figures out of the trapezium

The LENGTH of the lines on the x y & z axis multiplied. A trapezium is just a squashed box and we should all know how to calculate the volume of a box. Sounds like you have to do some additional calculations to find out the LENGTHS.

Volume of a trapezium = 1/2 (base a+base b) * height

As far as I'm aware a Trapezium is only a 2-dimensional shape, made up of 4 sides, 2 of which are parallel.
Maybe I'm wrong...

First find area:
Area of trapezium= 1/2 (a+b)h
Vol: = area of cross section x length

Divide it into triangles and use Pythagarous to work out the lengths of the sides then 1/2 base x height to work the volume of each triangle and then obviously add together.
I'm sure I spelt the fella's name wrong. But well.
