I don’t understand how the total resource needed is calculated to produce one Science pack 2 (green one).
According to the Factorio wiki,
Science pack 2 requires:
- 1 Inserter
- 1 Transport belt
Calculation for one Inserter
According to the Factorio wiki
an Inserter requires:
- 1 Green circuit
- 1 Iron gear
- 1 Iron plate
According to the Factorio wiki
a Green circuit requires:
- 3 Copper cables
- 1 Iron plate
According to the Factorio wiki
an Iron gear requires:
- 2 Iron plates
According to the Factorio wiki
Copper cable requires (to produce 2):
- 1 Copper plate (1.5 Copper plate to produce 3 units)
So, to produce 1 Inserter, we need 4 Iron plates + 1.5 Copper plates.
Calculation for Transport belt
According to the Factorio wiki
a Transport belt requires:
- 1 Iron gear ( requires 2 Iron plates )
- 1 Iron plate
So, to produce 1 Transport belt, we need 3 Iron plates.
Then, to produce one Science Pack 2, we need 7 Iron plates and 1.5 Copper plates.
Why is the total raw 5.5 Iron plates and 1.5 Copper plates?
Answer
The recipe for transport belts makes two belts, not one
