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!

Aluminum has a density of 2.7 g cm3 How many grams of aluminum make up a sheet of aluminum foil that is 45 cm 30 cm 0.0010 cm?
The foil has a volume of 45 cm x 30 cm x 0.0010 cm = 1.35 cm3. Density is mass per unit volume, so with a density of 2.7g/cm3, 1 cm3 of aluminum will weigh 2.7g. Therefore 1.35 cm3 will weigh 2.7 x 1.35 = 3.645g
