Constructions MATHSWATCH CLIP 47, 145, 146, 147 GRADE 2, 4 Before constructing an accurate net of a solid shape it is sensible to start by making a sketch of how we expect the completed net to look. Remember, in maths, a sketch is a diagram that is not drawn to scale. We should still use a ruler to do this. Suppose we want to construct the net of a cuboid of length 4 cm, width 2 cm and height 1 cm. We can sketch the net as follows: These are tabs.
