The room

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

Correct 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
