Đáp án+Giải thích các bước giải:

Bài 2:

$\text{1$m^{3}$ = 1000$dm^{3}$}$

$\text{209$m^{3}$ = 209000$dm^{3}$}$

$\text{34,6$m^{3}$ = 34600$dm^{3}$}$

Bài 3:

$\text{1$dm^{3}$ = $\dfrac{1}{1000}$$m^{3}$}$

$\text{2,643$dm^{3}$ = 0,002643$m^{3}$}$

$\text{51,17$m^{3}$ = 51170000$cm^{3}$}$

Bài 4:

$\text{7,528$m^{3}$ + 3,16$m^{3}$ + 21,05$m^{3}$ = 31,738$m^{3}$}$

$\text{34,62$m^{3}$ x 26,47$m^{3}$ = 916,3914$m^{3}$}$

$\text{18,5$m^{3}$ x 3,7 = 68,45$m^{3}$}$

$\text{24,42$m^{3}$ : 6,6 = 3,7$m^{3}$}$

$\text{27,42$m^{3}$ + 15,69$m^{3}$ + 7,03$m^{3}$ = 50,14$m^{3}$}$

$\text{59,67$m^{3}$ : 28,705$m^{3}$ = 2$m^{3}$}$

$\text{51,37$m^{3}$ x 8,3 = 426,371$m^{3}$}$

$\text{612,35$m^{3}$ : 18,5 = 33,1$m^{3}$}$
