What you will need to do is plug these numbers into your volume formula and solve for "w" (width).

V=l x w x h

138.24 = 9.6 * 3.2 * w

xmissalycatx · Answer

Multiply 9.6 and 3.2 which is 30.72 and you still have "w" left so now it is 30.72w.
Now you need to DIVIDE 138.24 and 30.72w so do:

138.24
------- =   w
30.72
