V= L*l*h; L=5*28=140 cm l=28:3.5=8 cm=> V= 140*28*8= 31360 cm la 3

1) V paralelipiped = Lx l x h
   h = 25 cm
   L = 5 x h
   l = h / 3,5 = 25 / 3,5 = 25 : 35/10 = 25x10 supra 35 = 8 cm ) dupa simplificari)
  l = 8 cm
  L = 5x h = 5 x 28 =  140
  L = 140 cm
  V paralelipiped = Lxlxh = 140 x 5 x 25 = 31360 cm^3 ( centimetri cubi)
