How much is 45 x 20 x 20 cm3?

180,000 mm3

18,000 cm3

1,800 dm3

180 m3

18 Dm3

1.8 hm3

0.18 km3

18,000 cm3 is correct but all the other numbers are wrong.

1 cm = 10 mm so 1 cm3 = 10 mm * 10 mm * 10 mm = 1000 mm3

so the correct values are 18,000,000 mm3 or 0.018 m3.

And 1.8*10-11 km3 , the correct answer is a billionth of the rubbish given in the prvious answer!
