Help With Ballast Calculation

Hi

I'm going to do a shed base 10x8 with an approximate fill of 150mm concrete.
How many Tonnes of ballast will I need and how many bags of cement?

also

I'm going to do a path 5m long 1m wide to the shed base with a fill of approx 100mm.
How much ballast and cement will I need for this?

Many Thanks In advance for your help.

Have a nice weekend..

I have done a complete renovation and discovered the hard way that £70.00 delivered for a cubic meter of concrete is not bad value for money

For both you're looking at 2 and half tonne of ballast and around 22 bags of cement which means alot of mixing not sure what the materials would cost you, if i was doing it and the access was ok i would get barrow mix 2 cubic metres.
