And with Toulouse comfortably beating the Dragons on Saturday night and with Glasgow already having claimed a Pool 6 victory of their own, Hanks knew only a win would suffice at Adams Park.
"We're wrapped with that. It puts us in a better position in the pool," said Hanks, after the 38-26, four-try triumph in Wycombe.
"This was a huge game for us. We had to win to stay in the pool. Even when you look at all the other pools and all the scenarios, they're all quite tight. I don't think you can afford to be none from two at this point.
"We're also wrapped to get a bonus point. We respect Glasgow too much to expect that we were going to get that."
Although all four tries were scored by backs, Hanks put the win down to the platform laid by his pack who bounced back convincingly following disappointment in Toulouse.
Even missing star names such as Phil Vickery, Tim Payne and Tom Rees, and with Joe Worsley only on the bench, Wasps were dominant in the set piece.
"Our young fellas really stood up today. In the Heineken Cup, if you don't front up in the set piece, you're in trouble aren't you?" added Hanks.
"We scrummed well on their ball and on our own. We were more in tune with the engagement than we were last week.
"That's a credit to our pack because we really got into them this week in terms of our expectations at the set piece.
"They fronted up and they delivered. That was a really pleasing aspect of the game for us.
"They're a big physical side Glasgow, so that makes the achievement even better."
