To find the total amount of liquid Kim has and convert it to cups, we first need to add up the fluid ounces of all the liquids:
- Milk: 18 fluid ounces
- Orange juice: 14 fluid ounces
- Apple juice: 16 fluid ounces
Now, we add these amounts together:
\[ 18 + 14 + 16 = 48 \text{ fluid ounces} \]
Next, we convert fluid ounces to cups using the conversion rate of 1 cup = 8 fluid ounces. To do this, we divide the total fluid ounces by the number of fluid ounces in one cup:
\[ \text{Total cups} = \frac{48 \text{ fluid ounces}}{8 \text{ fluid ounces per cup}} = 6 \text{ cups} \]
Therefore, Kim has 6 cups of liquid.
