Robert bought a 20 onces bottle

of water. How much water can the bottle hold in cups and fluid

ounces?

2.5 cups or 20 fl oz of water

Step-by-step explanation:

Ounces (oz) is used for weight measurements

Fluid ounces (fl oz) is used for capacity measurement for liquids.

1 fluid ounce (fl oz) ≅ 1 ounce (weight) for water only

so 20 ounce of water = 20 fl oz

1 fluid ounce = 0.25 cups

20 fluid ounces = 20*0.25 = 2.5 cups

So,

The bottle that Robert bought can hold

2.5 cups of water

20 fl oz of water
