Calculate the quantity for wet wall (New Wall)

Calculate the quantity for dry wall (Old Wall)




Length of wall = 80 feet

Height of wall = 10 feet


Total area covered by wall

= length x width

= 80 feet x 10 feet

= 800 sq.ft.


Calculate the quantity of wet wall

We have two type of gallons

1 UK Gallon = 4.54 litres

1 US Gallon = 3.785 litres

1 Gallon = 350 sq.ft. area covered.


Paint Quantity = (Area of wall / Paint covered area)

= 800 sq.ft / 350 sq.ft

= 2.285 gallon


Now convert into litre

= 2.285 x 3.785 (US Gallon)

= 8.64 litre


Price of paint = No. of litre required x Price of 1 litre

= 8.64 x current price
