Quantity of stone needed?

[onesiedale]

What is the calculation for working out the amount of hard core needed to put down?
I'm wanting to concrete a feed pad area approx 32m x 12m . Am thinking it will need top soil removal and 12" of stone base
How many tonnes of stone do i need?

80 to 100 ton

I make it 190-200 tons if you are using crushed limestone.

About what @Joseph says I reckon,

(32x12)x.3 divided by 12 , is about 9 eight wheeler loads.

Stone is around 2 ton a cubic metre

I work on stone at about 2t/m3 so about 230 tonnes

Round here that would be about £2200 of chalk

I use 2.24ton/m3 for stone so it works out to be 258ton for the dimensions given.
