Solid Figures

We are almost at the close of the chapter.
Some things to take note of:
1) You need to use dotted lines to show the hidden edges of the solid figures.
2) The diagrams should be clear enough to show the shapes of the faces.
3) We learnt about 2 kinds of pyramids. One has 4 triangular faces only (It is also called a tetrahedron) and the other has 4 triangular faces and 1 square.
4) Do not say "The cuboid has 4 triangles and 2 squares." You should say "The cuboid has 4 triangular faces and 2 square faces".
