A rectangular parallelepiped with dimensions of 2 dm, 5 dm and 6 dm was sawn into cubes with an edge

A rectangular parallelepiped with dimensions of 2 dm, 5 dm and 6 dm was sawn into cubes with an edge of 1 cm and folded into one row. How long is the row?

Let us express the dimensions of the parallelepiped in centimeters:
2dm = 20cm, 5dm = 50cm, 6dm = 60cm;
The volume of a rectangular parallelepiped is equal to the product of its sides:
V = 20cm * 50cm * 60cm = 60000cm ^ 3;
A cube with an edge of 1cm has a volume of 1cm ^ 3;
This means that from a parallelepiped you can get 60,000 cm ^ 3/1 cm ^ 3 = 60,000 cubes;
If the cubes are folded in a row, the length is:
60000 * 1cm = 60000cm = 600m.
