I have like 10 mins to figure this out-
since we have no idea how big the model is, we have no way to know how big the room is. But, when you figure that out, just divide the area by 400.
If the area of the model is m in^2, then the area of the room will be
(1.5m)^2 = (2.25m^2) ft^2
If the area of the model is m in^2, then the area of the room will be
(1.5m)^2 = (2.25m^2) ft^2
