Choose a box and work out the smallest rectangle of paper needed to
wrap it so that it is completely covered.
All Wrapped Up
Stage: 2 Challenge Level:
What makes one cuboid bigger than another? You may like to talk to
someone else about this!
Might it help to draw nets?
As you know the length and width of the paper, can you say anything
about the length, height and width of the cuboid looking at the net
Perhaps using a spreadsheet would help?
Or how about making some "skeleton" cubes out of construction
equipment or cubes?
The NRICH Project aims to enrich the mathematical experiences of all learners. To support this aim, members of the
NRICH team work in a wide range of capacities, including providing professional development for teachers wishing to
embed rich mathematical tasks into everyday classroom practice. More information on many of our other activities
can be found here.
