Answer 1

1) 250 dam = 250*1000=250000 = 25*$10^{4}$ cm ( 1 dam = 1000 cm)

2) 0.8924 km= 0.8924*100000= 89240 cm ( 1 km = 100000 cm)

3) 0.123 dm = 0.123*0.1 = 0.0123 m ( 1 dm = 0.1 m)

4) 1.234 hm = 1.234*1000= 1234 dm ( 1hm = 1000 dm)

5) 2.53 dam = 2.53*10000= 25300 mm ( 1 dam = 10000 mm)

6) 403.7 $cm^{2}$ = 403.7:10000 = 0.04037 $m^{2}$

7) 23.5 $dam^{2}$= 23.5*10000= 235000 $dm^{2}$

8) 0.987 $hm^{2}$ = 0.987*10000= 9870 $m^{2}$

9) 3456 $mm^{2}$ = 3456*0.01= 34.56 $cm^{2}$

10) 345 $cm^{2}$ = 345*0.0001= 0.0345 $m^{2}$

11) 47352 $cm^{3}$ = 3458*0.000001= 0.003458 $m^{3}$

12) 0.00234 $km^{3}$ = 0.00234 * 1000000000= 2340000 $m^{3}$

13) 0.374 $dam^{3}$ = 0.374*1000000000= 374000000 $cm^{3}$

14) 238L= 238*0.001= 0.238 $m^{3}$

15) 7.89L = 7.89 * 0.001 = 0.00789 $m^{3}$= 0.00789* 1000000000000=7890000000$mm^{3}$
