Would anyone know how to approach this question? Thank you!

Your room is 11 ft wide x 12 ft long x 8.5 ft high and has an air conditioner that exchanges air at a rate of 1200 L/min.  How long would it take the air conditioner to exchange the air in your room once?

I don't really know how to find the time since it doesn't tell me anything about the Liters. Hmmmmm..

Find the volume of the room in liters (hint: 1L = 1 dm³)
