Another one from the book, another horrible attempt at doing my own rendition of the book's picture. There are 9 matchsticks in the form of a cube. Suppose two of the matchsticks are removed. How could you rearrange the remaining seven matches so the still form the figure of a cube?

Well done, everyone. A lot of creative answers here on a puzzle that required some very creative thinking! I'll put spoiler box with the original answer, as well as some of the other answers you all came up with (really good stuff!!)

original answer -->

organize the matchsticks in the form of an "8" - 8 is the cube of 2.

Other ones

^3 (exponential cube)

27 (cube of 3)

If I missed any others, sorry.

You missed one:

"1" is the cube of "1", so arranging the matches to form a "1" would do it too.

What I find funny about Karlhite's answer of "8" above (with 8 being the perfect cube of 2), is that it means that the very first answer posted was correct, although it was by accident.

Bonanova suggested that if you looked at the cube from the front, without seing the sides, you could do so with 7 sticks. Essentially seeing only the front face and the top face. The arrangement of sticks that represents this IS an 8!

Wise man say: On multiple-choice test, better to be right by accident than wrong on purpose.
