How far will my 2007 Honda Accord Sedan go on full tank?

I'm planning a road trip soon and I'm wondering if it'll last about 400 miles on a full tank. Any of you car experts know? It's a V6. Eats mucho gas:/

This car has a 17.1 gallon fuel tank. It is rated at 29 to 34 highway. Assuming it gets 30 mpg which it should you can easily go 450 + miles on a full tank of fuel. If it is not getting at least 29 mpg on the highway then there's something wrong with your Honda.
