The room

The room has a cuboid shape with dimensions: length 50m and width 60dm and height 300cm. Calculate how much this room will cost paint (floor is not painted) if the window and door area is 15% of the total area and 1m2 cost 15 euro.

Correct result:

x =  8109 Eur

Solution:

a=50 m b=60 dm m=60/10  m=6 m c=300 cm m=300/100  m=3 m  S=a b+2 (a+b) c=50 6+2 (50+6) 3=636 m2 S1=(115/100) S=(115/100) 636=27035=540.6 m2  x=15 S1=15 540.6=8109 Eur
