4, assuming the final 0 is there for a good reason.
10 000 cm3
1 dm3 = 1000 cm3 :)
1 litre = 1,000 cm3 2 litres = 2,000 cm3 10 litres = 10,000 cm3 100 litres = 100,000 cm3 1,000 litres = 1,000,000 cm3
1 m = 100 cm So 1 m3 = 100*100*100 cm3 = 106 cm3 and 10 m3 = 107 cm3

The thickness (width or w) should be converted to cm (0.5mm=0.05cm), then find the Volume of the sheet. The Volume is r2*pi*w or (20 cm)2(0.05cm) * pi which equals 62.8319 cm3 or 63cm3 when considering the significant digits. You need to look up the density of aluminum somewhere. If you did you would probably find it to be somewhere around 2.70 grams per cm3 Density(p)=mass(m)/volume(v) If you multiply v by both sides of the equation you will have m=p*v mass=(2.70g/cm3)(63cm3)=170.1g or considering the significant digits 170 grams.
10 000 cm3
1 dm3 = 1000 cm3 :)
40.5 litres = 40,500 cm3
1000 cm3 = 1 litre
1 litre = 1000 cm3
Density = mass/volume Density = 22.4g/8cm3 = 2.8g/cm3 or 3g/cm3 if significant figures are considered.
The dimensions given for the copper cube make it 7.303 cubic centimeters in volume. To the justified number of significant digits, 7.303 is 389 cm3. The density of copper is given as 8.96 g/cm3 at 20C. Therefore, at that temperature, the mass of the cube would be grams. The gram molar mass of copper is the same as its gram atomic mass, 63.546, and the cube thus contains (3.49 X 104 )/63.456 or 54.9 moles, to the justified number of significant digits.
10^6 cm3=1dm3
There are 4.25 liters in 4250 cm3.
cm3 and cc are the same thing.
