A particular paint has a density of 0914gcm3 you need to cov

A particular paint has a density of 0.914g/cm3 .you need to cover a wall that is 7.6m long and 2.74m high with a paint layer 0.13mm thick.what volume of paint in liters is required ? what is the mass in grams of the paint layer?

Solution

Long = 7.6 m = 760 cm

hight = 2.74 m = 274 cm

thickness = 0.13 mm = 0.013 cm

Volume = long x hight x thickness = (760 cm) x (274 cm) x (0.013 cm) = 2707.12 cm3

given density = 0.914 g/cm3

density = mass /volume

So; mass of the paint = density x volume = (0.914 g/cm³) x (2707.12 cm³) = 2474.3 grams
