To determine the number of different size cubes that can be made with 64 multilink cubes, we need to find all the factors of 64. The factors of 64 are 1, 2, 4, 8, 16, 32, and 64. These factors correspond to the possible dimensions of the cubes that can be formed using the multilink cubes. Therefore, there are 7 different size cubes that can be made with 64 multilink cubes.
There are only four different configurations.
If you have got enough cubes, as many as you like.
Ignoring rotations, there are 3 distinct solutions.
You could try 14!
