(The significations of the symbols b, h, r may be 

 readily gathered from the preceding statements con- 

 cerning the volume of each figure.) 



The volumes of solids of irregular shape, such as 

 a lump of coal or a glass stopper, are usually very 

 difficult to determine by direct measurement. Other 

 methods of finding the volumes of such bodies are 

 given later.
