Block-shaped 32591

Štěpán painted a block-shaped steel board measuring 2.2 m, 1.5 m, and 1.6 m twice with a protective coating. How many kilograms of paint would he consume if he used 120g of paint per 1m2?

Correct answer:

x =  4.4256 kg

Step-by-step explanation:

a=2.2 m b=1.5 m c=1.6 m  n=2 S1=2 (a b+b c+c a)=2 (2.2 1.5+1.5 1.6+1.6 2.2)=25461=18.44 m2  ρ=120 g kg=120:1000  kg=0.12 kg  S2=n S1=2 18.44=25922=36.88 m2  x=S2 ρ=36.88 0.12=4.4256 kg
