Defuse The Bomb - Surface Area (Cubes and Cuboids)

I am going to be teaching Year 7 some surface area of cuboids and cubes but only had one of these involving prisms which might be a step too far at this point. This was what I came up with. The answers are on the sheet (although there are more answers than questions to avoid default answers at the end) which gives students the confidence to keep going if they are getting questions correct allowing the teacher to help those who really need it.
