Express 6.45 liters in cubic centimeters.

In order to answer this question, we need to recall some of our conversions between units of capacity and volume. We know that one milliliter of capacity is equal to one cubic centimeter of volume. We also know that there are 1000 milliliters in one liter. This means that in order to convert from liters to milliliters, we need to multiply by 1000. 6.45 multiplied by 1000 is 6450. When multiplying by 1000, all of our digits move three places to the left. This means that 6.45 liters is the same as 6450 milliliters.

As the ratio of milliliters to cubic centimeters is one to one, 6450 milliliters is the same as 6450 cubic centimeters. A capacity of 6.45 liters is the same as a volume of 6450 cubic centimeters.
