Question

Question 1 1200 m2 = km2. Question 2 0,02 h = s. Question 3 2,75 ha = m2. Question 4 7,2 dm 2 = cm2. Question 5 7 m3 = dm3. Question 6 6,5 km = m. Question 7 12 l = dm3. Question 8 36 km/h = m/s. Question 9 5 g/cm3 = kg/m3. Question 10 750 m = km. Question 11 2,5 dm = cm. Question 12 4 dm2 = m2.

Answer 1

Question 1

1200 m2 =0,0012 km2.

 

Question 2

 0,02 h = 72 s.

w minucie jest 60 sek, minut w godzinie 60 czyli sekund w godzinie 3600

0,02*3600=72 

 

Question 3

2,75 ha = 27 500m2.

 

Question 4

7,2 dm 2 = 720cm2.

 

 

Question 5

7 m3 = 7000 dm3.

 

Question 6

6,5 km =6500 m.

 

Question 7

12 l =12 dm3.

 

Question 8

36 km/h =10 m/s.

36000m/h

h=3600s

36000:3600=10m/s 

 

Question 9

5 g/cm3 =5000kg/m3.

5*1000=5000 

 

Question 10

750 m =0,75 km.

 

Question 11

 2,5 dm =25 cm.

 

Question 12

4 dm2 =0,04 m2.
