Maths Week: Your Tuesday puzzle

Figure it out.

IT’S MATHS WEEK, and as is our annual tradition here, we’re setting you a puzzle a day with all answers published on the site on Sunday. 

Get puzzling!


A pentomino is the shape formed by joining 5 squares along their edges. There are 12 distinct different shapes possible and 9 are presented here.

A cube has 6 faces but some pentominoes can be folded (along edges of its constituent squares) to make an open box (with 5 faces). Which of the pentominoes shown can be folded thus?


All answers will be published on on Sunday
