The emery papers should be of very good quality in respect of uniformity of particle size. Four grades of abrasives used are: 220 grit, 320 grit, 400 grit and 600 grit (from coarse to fine); the 320 grit has particle sizes (of the silicon carbide) as about 33 microns and 600 grit that of 17 microns (1 micron = 10-4 cm).

An object’s volume is the space the object occupies. For example, this book has volume because it takes up space. Volume can be determined in several different ways. The method used to determine volume depends on the nature of the matter being examined. The book’s volume can be found by multiplying the book’s length, width, and height.
