How many smaller cubes with edges measuring 2 decimeters can be obtained from a cube with a 1-meter edge?

Explanation

The volume of the large cube is 1 m × 1 m × 1 m = 1 cubic meter. Since 1 meter equals 10 decimeters, the cube's edge is 10 dm. Each smaller cube has an edge of 2 dm, so the number of smaller cubes along one edge is 10 dm ÷ 2 dm = 5. Therefore, the total number of smaller cubes is 5 × 5 × 5 = 125.
