How we got this

1
Net painted area
A = (Wall length × Height + Ceiling − Openings) × No. of such rooms
= (0 × 0 + 0 − 0) × 1
= 0 m²
2
Total area to cover
A = Painted area × No. of coats
= 0 × 0
= 0 m²
3
Paint volume
Litres = A / Coverage
= 0 / 0 m² per L
= 0 litres
4
Packing
Cans = ceil(Litres / 4 L)
= ceil(0 / 4)
= 0 cans of 4 L
Buy 20 L buckets where the quantity allows — the rate per litre drops.
5
Surface preparation
Putty = Area × 1.2 kg/m² ; Primer = Area / Coverage
= 0 × 1.2 kg and 0 / 0
= 0 kg putty · 0 L primer

The theory behind it

Method used: Coverage-rate method — spreading rate per litre, IS 2395 painting practice

Paint quantity = painted area × number of coats ÷ spreading rate. The spreading rate printed on the can (usually 10–14 m²/L per coat for emulsion) already accounts for a normal, puttied surface; a rough or fresh plaster surface drinks far more on the first coat.

Assumptions used

•Coverage 10 m²/litre per coat unless you change it.
•Primer: 1 coat at the same coverage.
•Wall putty ≈ 1.2 kg/m² for 2 coats.
•Area is the net painted surface after deducting openings.
