A cube with an edge of 2 dm was cut into cubes with an edge of 1 cm, which were then laid out in a row one after the other. How long is the resulting row?

Let’s define the area of this cube in square centimeters.

The side of the cube in centimeters will be:

2 dm = 20 cm,

therefore, the volume of a cube in cubic centimeters will be:

20 ^ 2 = 400 cm2

If you add 400 of these cubes in a row, you get a row of 400 cm or

400: 100 = 4 m.

Answer: the length of the row will be 4 m.
