How long will the strip be if a cubic kilometer is cut into cubic meters and laid out in a single line?

#
In one cubic kilometer - a billion cubic meters.

## Solution

In one cubic kilometer, there is a billion cubic meters (1000 in length, 1000 in width, and 1000 in height). If all of them are laid out in a row, it would form a strip one billion meters long, i.e., one million kilometers.

## Answer

1000000 km.
