Đáp án: $\text{+}$ Giải thích các bước giải:

3$\text{ $dm^3$ 25 $cm^3$ = 3025 $cm^3$}$

$\text{→ Ta có: 3 $dm^3$ = 3 × 1000 = 3000 $cm^3$ = 3000 + 25 $cm^3$}$

$\text{→ Vậy 3 $dm^3$ 25 $cm^3$ = 3025 $cm^3$}$

$\text{______________________________________________}$

$\text{8 $dm^3$ 45 $cm^3$ < 8,45 $dm^3$}$

$\text{→ Ta có: 45 $cm^3$ : 1000 = 0,045 $dm^3$ = 8,045 $dm^3$.}$

$\text{→ Vậy 8 $dm^3$ 45 $cm^3$ < 8,45 $dm^3$}$

$\text{______________________________________________}$

$\text{5 $dm^3$ 9 $cm^3$ < 5090 $cm^3$}$

$\text{→ Ta có: 5 × 1000 = 5000 $cm^3$ = 5000 + 9 = 5009 $cm^3$}$

$\text{→ Vậy 5 $dm^3$ 9 $cm^3$ < 5090 $cm^3$}$

$\text{______________________________________________}$

$\text{10 $m^3$ 810 $dm^3$ > 10,8 $m^3$}$

$\text{→ Ta có:}$

$\text{- 10 $m^3$ = 10 × 1000 = 10000 $dm^3$ = 10000 + 810 = 10810 $dm^3$}$

$\text{- 10,8 $m^3$ = 10,8 × 1000 = 10800 $dm^3$}$

$\text{→ Vậy 10 $m^3$ 810 $dm^3$ > 10,8 $m^3$}$

$\text{______________________________________________}$
