REAL WORLD MATHS

Boxes need tabs

When we draw a net for a real 3D

shape, we usually include tabs. Tabs

are flaps added to some of the shape’s

sides so that we can stick the box

together more easily. If you take an

empty cereal box apart, you’ll see the

tabs that have been glued to some of

the panels to form the box.
