About This Set
Set 1 checks the basic method for every solid in the chapter, one or two steps at a time. The questions are mixed, so first decide which solid you are looking at and which measure is asked: curved surface, total surface or volume. Most marks in a set like this go on the radius taken as the diameter, the left out of a cone or pyramid, or cm³ not changed to litres (1 litre cm³). Allow about 30 minutes. If 20 or more are right, go on to Practice Set 2; if not, reread the section on each solid you missed.
