Fermi approach is all about "estimates". So start estimating......

Please show us what you have tried and exactly where you are stuck.

The whole point of a Fermi problem is to do it yourself, using whatever knowledge you have. How big do you think a typical room is? How many rooms do you think a typical house has? And so on.

If you want help, you must show us your attempt. Then we might suggest ideas you are missing, or things you could ignore.

Thanks. I know its hypothetical approach to solve Fermi problem.

Is there any specific approach I can use to validate my calculations

Not really. The whole point is to come up with an order of magnitude.. It is a very rough estimate. It might be off by a factor of 10, maybe even 100. Do you think one litre is enough to paint a room? If not, how about 10 liters? 100? How many rooms in a house? 1? 25? 50? 125??
