According to http://www.pavingexpert.com/calcall.htm#focus11 you will
need 320 Kg cement, 600 Kg sand, 1200 Kg gravel and 300 L water.
It might be easier to phone a local ready-mixed firm or mix-a-mate type.
Well, yes and no. If the conservatory is 3m by 4m, it would give you
less than 100mm thickness.
I managed to lose 4 cubic metres of concrete when I rebuilt my drive
last year, and that was just for the edging!
Sounds like you were robbed.
Measure the space out in gunny sacks and order that many (+ a few extra)
bags of sand and gravel (50/50) and order 1/6 as many hundred-weight
bags of cement.
If you need a more cement go and fetch it in the car.

So obviously it's going to weigh 1 helluva weight.
