a) 1m3 = 1000dm3
- 1m3 = 1000dm3
- 5,216m3 = 5,21 x 1000dm3 = 5216dm3
- 13,8m3= 13,8x 1000dm3 =13800dm3
- 0,22m3 = 0,22x 1000dm3 =220dm3
b) 1dm3 = 1000cm3
- 1dm3 = 1000cm3
- 1,969dm3 = 1,969 x 1000 cm3 = 1969cm3
- $\frac{1}{4}$m3= $\frac{1}{4}$x 1000dm3= 250 x 1000cm3=250000cm3
- 19,54m3 = 19,54 x 1000dm3 = 1954 x 1000cm3 = = 19540000cm3
