Question

2,5 m² na cm²

1800 mg² na g²

12 mm² na m²

Zo obliczeniami proszę. ;)

Answer 1

2,5 *10000= 25000cm^2

1800 mg^2 : 1000000= 0,0018g^2

12 mm^2 : 1000000 = 0,0012 m2

Answer 2

2,5 cm² = 2,5 * 10 * 10 = 250 mm²

1 g² = 1*1000*1000=1000000mg²

wiec

1mg²=0,000001g²

1800mg²=0,0018g²

 

1m²= 1*1000*1000=1000000mm²

 1mm²=0,000001m²

12mm²=0,0012
