a)
1cm3 = \(\displaystyle {1 \over {1000}}\)dm3 = 0,001dm3
5,216m3 = 5,216 x 1000dm3 = 5216dm3
13,8m3 = 13,8 x 1000dm3 =13800dm3
0,22m3 = 0,22 x 1000dm3 = 220dm3
b) 1dm3 = 1000cm3
1,969dm3 = 1,969 x 1000cm3 = 1969cm3
\(\displaystyle{1 \over 4}\)m3 = \(\displaystyle{1 \over 4}\) x 1 000 000cm3 = 250 000cm3
19,54m3 = 19,54 x 1 000 000cm3 = 19 540 000cm3
