Which is a better estimate for the volume of a laundry detergent cap?6 fluid ounces    6 pints

The better estimate for the volume of a laundry detergent cap would be 6 fluid ounces.

Here's why:

1. Understand the units: A fluid ounce is a unit of volume typically used for measuring liquids and is smaller than a pint. There are 16 fluid ounces in a pint.

2. Compare the units to the object: A laundry detergent cap is quite small and typically holds a small amount of liquid.

3. Make an educated guess: Given the small size of a laundry detergent cap, it's unlikely to hold 6 pints of liquid, which is equivalent to 96 fluid ounces. Therefore, 6 fluid ounces is a more reasonable estimate for the volume of a laundry detergent cap.
