Painter

How many euros we will pay for repainting the room shaped cuboid with a length of 4.5 meters, width of 2.5 meters and a height of 3 meters, if for 1 m2 with paint we pay € 1.5?

Correct result:

x =  159.75 Eur

Solution:

c=1.5=3 eur/m2 a=4.5 m b=2.5 m c=3 m  S=a b+2 (a+b) c=4.5 2.5+2 (4.5+2.5) 3=2134=5314=53.25 x=c S=3 53.25=6394=15934=6394 Eur=159.75 Eur
