This programs shows how to measure the dimensions of common 3D objects. The calculations needed to obtain their surface areas and volumes are also illustrated. The solids featured are polygon-based prisms and pyramids, cones, cylinders and spheres. The recognizable objects used in this program vary from well-known snack containers to the pyramid of Cheops. Worked examples with full setting out and rounding to two decimal places are clearly illustrated and there are opportunities for student practice within the program.
