Answer 1

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

$\frac{6oz}{day}\cdot\frac{29.574mL}{1oz}\cdot\frac{1L}{1000mL}\cdot\frac{1m^3}{1000L}\cdot\frac{365days}{1year}$

Observe that we have 1 ratio or fraction for each equivalent between units. Now, we solve the products.

$\frac{64,767.06m^3}{1,000,000year}\approx0.06(\frac{m^3^{}}{\text{year}})$

Therefore, 6 fluid ounces per day is equivalent to 0.06 cubic meters per year.
