You don't have to google it. First of all, "pad" is not illogical, and it's arguably a more familiar word to non-native speakers than "extrude". Secondly, the tool's icon looks just like an extruded cube, so it's what you're likely to reach for first if you're just experimenting for the first time. It's also right next to the revolve tool, just like in SolidWorks. When you click on it you'll immediately see a preview of the extruded cube that you expected, so you did the right thing. And lastly, if the name of the pad tool bugs you a lot, you can submit a patch.
