The cross-product vector 
v × 
w
is perpendicular to the plane
formed by the vectors 
v and 
w.

rules for generating graphics on printers and computer screens, and use vector
concepts in drawing letters as well as pictures. Graphics files on your computer
that end in .GIF or .JPG are raster files. Vector files (geometric files) are easier to
modify than raster files. Raster files display faster than vector files, although the
high speed of modern processors makes this a negligible difference to the ordi-
nary computer user. Vector descriptions of images are used for computer identifi-
cation of faces, for translating handwriting into computer text, for descriptions of
protein structures, and for the location of tumors in medical CAT scans.

VOLUME
Volume describes the amount of space contained in a three-dimensional
object. Almost every object we use has volume, due to having depth. Even a
sheet of paper has volume, because it has thickness, although a very thin one. If
an object, such as paper, does not have volume, then it could be stacked indefi-
nitely without having any height. You can estimate the thickness of a sheet of
