This is an interlocking cube puzzle. It wil take 11 steps to remove the first part out of the cube. If you give this cube disassembled to someone it will probably take them very long to solve.
This cube is a bit easier than the white green version. However, solving this cube takes more steps. Personally I think the solution is a bit more creative.
A burr puzzle can be ranked in two ways: level and steps. The steps are the total amount of movements which is needed to disassemble all parts. For this cube it takes 30 linear steps to completely dissemble it. The Level of the puzzle is the total amount of steps which it takes to remove the first part. For this cube it takes 11 linear steps before you can take out the first part. To take all parts apart it takes respectively 11, 5, 6, 4 and 4 steps.
