Hint 2 of 2
Look at each cube and try to slice it into 4 pieces that are all the same shape as Erik's brick.
Show solution
Approach: match the cube whose four equal pieces are all the same brick shape
- Erik has 4 copies of one single brick shape, so the cube must split into 4 pieces that all look exactly like that brick.
- Go cube by cube and try to cut each one into 4 identical bricks.
- Only the cube in C comes apart into 4 bricks that match Erik's, so that is the one he can build.
- So the answer is C.
