1 m^3 of olive oil has a mass of 920 kg ====>
1 cubic decimeter (=same as 1 liter) of olive oil has a mass of 920 g.
460 g is the half of 920 g.
Hence, the volume of 460 g of olive oil is half of a liter, or, which is the same, half of a cubic decimeter, or 500 cubic centimeters.
1 kilogram = 1000 grams.
1 m^3 = 1000 cubic decimeters = 1000 liters.
1 cubic decimeter = 1 liter = 1000 cubic centimeters.
