To find the number of bottles of water that can be filled from the barrel, we need to know the volume of the barrel. Without this information, we cannot accurately calculate the number of bottles that can be filled.
Once we have the volume of the barrel, we can use the following formula to find the number of bottles that can be filled:
Number of bottles = Volume of barrel / Volume of each bottle
For example, if the volume of the barrel is 100 litres and each bottle holds 0.73 litres, the number of bottles that can be filled would be:
Number of bottles = 100 / 0.73 = 136.98
Since we cannot fill a partial bottle, we would round down to the nearest whole number, giving us a total of 136 bottles that can be filled from the barrel.
