Question

Wyrać w litrach i mililitrach objętosć porostopadłościanu o wymiarach a )30cm 20cmc 7 dm b)45 cm 3dm 10 dm

Answer 1

a)

a=30 cm

b=20 cm

c=7 dm = 70cm

V= a*b*c

V=30*20*70

V=42000 cm3 = 42000 ml = 42 l

 

b)

a=45 cm

b=3 dm = 30cm

c=10 dm = 100 cm

V=a*b*c

V=45*30*100

V= 135000 cm3 = 135000 ml = 135 l

Answer 2

a = 30cm

b=20cm

c = 7dm = 70cm

 

V = abc = 30*20*70 = 42 000 cm³ = 42 000 ml (1cm³= 1ml)

 

a = 30cm = 3dm

b=20cm = 2dm

c = 7dm

(1dm = 10cm)

 

V = 3*2*7 = 42 dm³ = 42 litry (1dm³= 1 litr)

 

 b)45 cm 3dm 10 dm

45cm = 4,5dm

30cm = 3dm

100cm = 10dm

 

V = 45*30*100 = 135 000 cm³ = 135 000 ml

V = 4,5*3*10 = 135dm³= 135 litrów
