The problem asks to convert 250 cubic centimeters to liters.

1. Problem Description

The problem asks to convert 250 cubic centimeters to liters.

2. Solution Steps

First, we need to know the conversion factor between cubic centimeters ($cm^3$) and liters (L). We know that:

$1 L = 1000 cm^3$

To convert $250 cm^3$ to liters, we can use the conversion factor by dividing 250 by 1000:

$L = \frac{cm^3}{1000}$

$L = \frac{250}{1000}$

$L = 0.25$

3. Final Answer

The cup holds 0.25 liters of water.
