Question

18. The mass of a box with 20 similar bottles of cooking oil is 18.6 kg. The mass of the empty box is 1.4 kg. What is the mass of each bottle of oil in kilograms?

Answer 1

18.6-1.4=17.2 kg

17.2/20 bottles=0.86 kg per bottle of oil

Answer 2

Explanation:

Total mass = 18.6kg

Mass of empty box = 1.4kg

no. of bottles = 20

subtract the mass of the empty box from the total mass to get the mass of only the bottles: 18.6 - 1.4 = 17.2kg

Mass of the 20 bottles = 17.2kg

To get the mass of each bottle, we divide the mass of the bottles by the number of bottles.

therefore: 17.2 ÷ 20 = 0.86 kg

Therefore the mass of each bottle = 0.86kg.

Hope this helps.

Good luck ✅.
