The basic things you should know to calculate the volume of 1 bag of cement are:

1. Density of cement = 1440 kg/ m³
2. 1 bag = 50 kg of cement
3. 1 m³ = 35.3147 cubic feet
4. 1 m³ = 10³ liters

Let’s see how can we calculate the volume of 1 cement bag by using all the values mentioned above.

The volume of cement bag in meter cube (m³)

Number of cement bags required in 1 m³ = Weight of cement in 1 m³/weight of cement in one bag

i.e., number of cement bags required in 1 m³ = 1440/50 = 28.80 No’s

∴ Volume of one cement bag = 1/28.8 = 0.034722 m³

Volume of cement bag in cubic feet (CFT)

since, 1 m³ = 35.3147 cubic feet = 28.80 No. of bags 

∴ Volume of one cement bag = 35.3147/28.80 = 1.226 CFT (cubic feet)

Volume of cement bag in Litres

since, 1 m³ = 10³ liters

Volume of one cement bag = 0.0347 m³ = 0.034722 x 10³ = 34.4722 litres

∴ Volume of one cement bag = 34.4722 litres
