That is a lot of concrete too mix by hand!
For a c20/25 MIX you would need approximately
308 25kg bags of cement
40 tonnes of ballast please note not 40 jumbo bags as these are not a tonne they are about 800kg
4225 litres of water.
It would be alot cheaper to get ready mixed concrete and a pump.

So your shed base is approx 15m x 15m or 50ft x 50ft if you lay concrete 100mm thick????? That’s about the size or 2/3 houses
Are you sure it’s 24 cubic metres and not 24 sq metres
Ready mix concrete is normally around £140 m3 and you want 24 x £140 = £3360?
Or 24m2 ready mix at 100mm thick is 2.4m3 = £336
