This is how i deduce ... there may be other better methods ... 😉 B.. D ... E are out cos it will not fold to become a square box ... left with A & C .... Can use a cube/physical box/ cut out of the question to let the kid visualise why its C & not A

Another learning point would be to eliminate those which don't have 6 sides which the square box (with a cover) will have.

At 70 mins, faster machine printed 6x70=420 more and stop. Slower machine will need another 30 mins to match the same total printed by the faster machine. Therefore 30 mins print 420, 1 min print 14. Therefore 100 mins print 1400 pages. Therefore total pages printed is 1400x2 = 2800
