Question

calculati si apoi completati spatiile punctate:
a)2500 cm cubi + 1,8 dm cubi=....l
b)1500 cl+300 cm cubi=....l
c)52 kl-25000000 cm cubi= m cubi
d)7,45 m cubi-250000 cm cubi=.... kl
e)3,85 m cubi+0,15 kl=.....l
f)12,65 cm cubi+0,0135 dl=....ml

Answer 1

a)2500cm cubi=2,500dm cubi=2,5l

1,8 dm cubi=1,8l

2,5l+1,8=4,3l

b)1500cl=15l

300cm cubi=0,3 dm cubi=0,3 l

15l+0,3l=15,3l

c)52kl=52000 l=52000dm cubi=52m cubi

25000000cm cubi==25000 dm cubi=25 m cubi

52 m cubi-25 m cubi=27 m cubi

d)7,45 m cubi=7450 dm cubi=7450 l=7,45 kl

250000 cm cubi=250 dm cubi=250 l=0,25 kl

7,45 kl-0,25 kl=7,20 kl

e)3,85 m cubi=3850 dm cubi=3850 l

0,15 kl=150l

3850l+150l=4000l

f)12,65 cm cubi=0,01265 dm cubi=0,01265l=12,65 ml

0,0135 dl=1,35 ml

12,65 ml+1,35 ml=14 ml
