To express the given rate in cubic meters per year, we have to consider the following equivalences.
• 1 cubic meter equals 1000 liters.
,
• 1 liter equals 1000 milliliters.
,
• 1 fluid ounce equals 29.574 millilters.
,
• 1 year equals 365 days.
To transform, we have to express each equivalence as a ratio, as follow
![(6oz)/(day)\cdot(29.574mL)/(1oz)\cdot(1L)/(1000mL)\cdot(1m^3)/(1000L)\cdot(365days)/(1year)](https://img.qammunity.org/2023/formulas/mathematics/college/yul0twyswm5a3er1aeo3qoczjw92ebv4f1.png)
Observe that we have 1 ratio or fraction for each equivalent between units. Now, we solve the products.
![(64,767.06m^3)/(1,000,000year)\approx0.06(\frac{m^3^{}}{\text{year}})](https://img.qammunity.org/2023/formulas/mathematics/college/21u52ibjte3ni6awbi538lenki78yp2rl0.png)
Therefore, 6 fluid ounces per day is equivalent to 0.06 cubic meters per year.
