If 5 letters of paint covers 20 square metres how many litres are required to cover 400 square meters
It is not possible to determine the answer without additional information about the density and thickness of the paint being used. Different paints have different densities and will therefore require different amounts of paint to cover the same area.
To find out how many litres of paint are required to cover 400 square meters, you need to determine the conversion factor between square meters and litres for the specific paint being used.
Since you mentioned that 5 letters of paint cover 20 square meters, we can calculate the conversion factor as follows:
Conversion factor = 20 square meters / 5 litres
To find out how many litres are required to cover 400 square meters, you can use the conversion factor:
Required litres = (400 square meters) / Conversion factor
Let's calculate the conversion factor first:
Conversion factor = 20 square meters / 5 litres = 4 square meters per litre
Now, let's calculate the required litres for 400 square meters:
Required litres = (400 square meters) / (4 square meters per litre)
Required litres = 100 litres
Therefore, you would require 100 litres of paint to cover 400 square meters.
