How do i find 1800 ml of water would fill a ________ cm3 container

Not sure what you're asking, but 1800ml of water can fill a 1800cm3 container.

As a side note: ml and cm^3 are basically the same, but cm^3 is volume. 10ml is 10cm^3 and 1ml is 1cm^3.

To find the volume of a container that can hold 1800 ml of water, we can use the conversion factor that 1 ml is equal to 1 cm^3.

First, convert 1800 ml to cm^3:
1800 ml * 1 cm^3/ml = 1800 cm^3

Therefore, a container with a volume of 1800 cm^3 can hold 1800 ml of water.
