Question

3. Jakie liczby należy wpisać w kwadraciki?

a) 1 km2 = 10_ m2

100 km2 = 10 _m2

b) 1m2 = 10 _cm2

105 m2 = 10_ cm2

c) 1 cm2 = 10_ mm2

1m2 = 10 _mm2

d) 1 km3 = 10 _m3

1km3 = 10 _cm3

_ - kwadracik

Answer 1

3.

a)1km^2=1km*1km=1000m*1000m=1 000 000m^2=10^6 m^2

   100km^2=1km*100km=1000m*100000m=100 000 000m^2=10^8 m^2

b)1m^2=1m*1m=100cm*100cm=10 000cm^2=10^4 cm^2

   105m^2=1m*105m=100cm*10500cm=1 050 000cm^2=10*6+5*10^4 cm^2

c)1cm^2=1cm*1cm=10mm*10mm=100mm^2=10^2 mm^2

   1m^2=1m*1m=1000mm*1000mm=1 000 000mm^2=10^6 mm^2

d)1km^3=1km*1km*1km=1000m*1000m*1000m=1 000 000 000m^3=

   =10^9 m^36

   1km^3=100000cm*100000cm*100000cm=

   =1 000 000 000 000 000cm^3=10^15 cm^3

 

km^2=km kwadratowych

km^3=km sześciennych

10^15=10 do potęgi 15

i tak dalej...
