Correct answer:

w =  213.1 cm

Step-by-step explanation:

N=5000 a=20 m b=15 m h=20 cm m=20:100  m=0.2 m  V=N 0.30 0.20 0.10=5000 0.30 0.20 0.10=30 m3  o=2 (a+h+b)=2 (20+0.2+15)=5352=70.4 m  S=h o=0.2 70.4=25352=14.08 m2  c=V/S=30/14.08=1763752.1307 m  w=c cm=c 100  cm=2.1307 100  cm=213.1 cm=213.1 cm
