A cube with an edge of 20 cm was cut into cubes with an edge of 2 cm. Then all these cubes were laid in a continuous row. What is the length of this row?
Find the number of cubes along the edge of the large cube:
20: 2 = 10.
Then the total number of cubes will be equal to:
10 * 10 * 10 = 1000 pieces.
If you put them in one continuous row, then its length will be equal to the edge of the cube multiplied by their number:
2 * 1000 = 2000 cm.
