Torque and Chrome

How to find Torque with this information?

A student working on their car needs to tighten the mounting bolts to a specified torque. If the student is using a 9.4 inch long wrench and is applying 16.8 pounds of force, what torque in Newton-meters (Nm) are they appling to the bolts? That is the question I was given. I don't even know where to begin. Could someone help me out? I can maybe answer one of your questions in exchange.

1. Torque is simply force x distance. 1 lbf = 4.448 N 1 inch = 0.0254 m So applied torque = 9.4 x 0.0254 x16.8 x 4.448 = 17.8 Nm
