Cube It Together! (back to problem 238)

 

a) (warmup) Start with a 2" by 6" rectangle. Say how to cut it up in the fewest number

of pieces and rearrange into a 3" by 4" rect.

 

b) Start with a block 8cm by 8cm by 27cm.

Find the fewest number of pieces to cut it into to rearrange into a 12 by 12 by 12 cube.

Explain precisely how to do it. (Dan's note: I actually did this, with cheese!)

Show your reasoning. Simple GIFs ok if necessary
