Answer: You will need 18 containers of 1-quart to fill the gearbox with 16.3 liters of oil.
Step-by-step explanation:
Knowing that you have 1-quart containers, you need to make the conversion from quarts to liters. This is:
[tex]1\ quart=0.946\ liters[/tex]
Now, since the gearbox holds 16.3 liters of oil, you can divide the volume of oil the gearbox holds by the volume of a container (which is 0.946 liters or 1-quart) to calculate how many containers of 1-quart you will need to fill the gearbox with 16.3 liters of oil.
[tex]number\ of\ containers=\frac{16.3\ liters}{0.946\ liters}=17.2[/tex]
Based on the result, you will need 18 containers of 1-quart to fill the gearbox with 16.3 liters of oil.
