answer:
To find the weight of an empty barrel, we need to subtract the weight of the wine from the total weight of the barrel.
1. Calculate the weight of the wine:
- The volume of wine is given as 6 m^3.
- The density of the wine is given as 850 kg/m^3.
- To find the weight of the wine, we can multiply the volume by the density: 6 m^3 * 850 kg/m^3 = 5100 kg.
2. Calculate the weight of the empty barrel:
- The total weight of the barrel is given as 5500 kg.
- To find the weight of the empty barrel, we subtract the weight of the wine from the total weight: 5500 kg - 5100 kg = 400 kg.
Therefore, the weight of the empty barrel is 400 kg.
