How many kg of paint will we use to paint the walls and ceiling of a room with a length of 9m, a width of 6m, and a height of 3.2m if 1kg of paint is enough for approximately 6m square? Subtract 6 square meters from the surface of the walls, which are the doors and windows.

Correct answer:

m =  24 kg

Step-by-step explanation:

a=9 m b=6 m c=3.2 m S1=6 m2  S2=a b+2 c (a+b)=9 6+2 3.2 (9+6)=150 m2  S=S2S1=1506=144 m2 ρ=1/6=610.1667 kg/m2  m=ρ S=0.1667 144=24 kg
