'Auditorium Steps' printed from  Show menu  The challenge
follows on from Wrapping Presents. Here's a model of a small
auditorium. There are four squares at the bottom inside and
there are three sets of steps to the top. To help to visualise
it I've coloured each face of the cube blocks according to which
way they are facing. Your challenge is to imagine that this is a
small model that is a present for someone and so it has to be
carefully wrapped up with paper. We do not want to waste paper
so the wrapping needs to be from a cut shape so that each
visable face (no matter where you are viewing it from) needs to
be covered CLOSELY with ONE LAYER OF PAPER ONLY and there is to
be just ONE piece of wrapping paper. Draw the shape of that
wrapping paper which would need to be cut out. Describe how you
went about it and say what you can about the paper shape. Then
ask yourself "I wonder what would happen if I ...?"
