The room

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

Final Answer:

x =  8109 Eur

Step-by-step explanation:

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=52703=540.6 m2  x=15 S1=15 540.6=8109 Eur
