Question 214626
Volume(V) of the toolbox =Length(L) times Width(W) times Height(H) or V=LWH

Now we are told the length (20 in)and the height (6 in) and the volume (960 cu in).  So our equation to solve is:
20*6*W=960 or
120W=960  divide both sides by 120
W=8 in----------------it will fit on the shelf

CK
960=20*6*8
960=960

Hope this helps---ptaylor
