Solution
The volume of a cube = (side)3. Given, the volume of the bigger cube = 512 m3. The number of cubes of side length 1 m formed by cutting the cuboid = 512m313m3 = 512. The number of cubes of side length 2 m formed by cutting the cuboid = 512m323m3 = 64. The number of cubes of side length 4 m formed by cutting the cuboid = 512m343m3 = 8. The number of cubes of side length 8 m formed by cutting the cuboid = 512m383m3 = 1.
