 Numbers in (red) are total possible solutions for this shape.Notes:Similar to the 1x5x10, the 1x5x11 has limited use of sub shapes. Here is one solution using the 1x3x4. The 1x5x12 gets back to the realm of fairly easy (with 126 solutions) and the usage of many sub shapes. Can you spot them all in this solution? You should see 4 separate sub shapes.
