the site calculator asks for compacted depth (40mm) and says i need 4 tons of sharp sand for 7mx8m.

But other site calculators ask for actual sand depth.
60mm (before compacting), and they say 7 tons.

I've shovelled out 4 tons already from jumbo bags in my works van.

Can anyone confirm what I actually need?

To which site calculators are you referring?

There's only one on this site that determines bedding sand quantity for block paving.

4 metric tonnes
approx 5 bulk bags

PS: the other calculators were just sand suppliers from google who were not talking about compacted sand
