Cati litri de apa incap intr-un acvariu in forma de paralelipiped dreptunghic ce are urmatorele dimensiuni:a]L=30 cm,l=2,5 dm,h=40 cm.b]L=15 dm,l=1,2 m,h=38 cm


Răspuns :

a) Transformam in dm neparat.

 L= 30 cm = 3dm
 l = 2,5 dm
 h= 40 cm = 4 dm

V=l x L x h
  =3 x 2,5 x 4
  =[tex] 30^{3} [/tex] ⇒ 15l


b)

L=15dm
l=1,2m⇒1,2m=12dm
h=30cm = 30cm=3dm

V=15dm·12dm·3dm
V=540dm³⇒540dm³=540l
