A cubic kilometer is 1000 meters by 1000 meters by 1000 meters which will total to 1,000,000,000 cubic meters, which is very much why km3 is very seldom used

123 m3 is 1.23 x 10-7 km3

There are 1000m in a km. Thus if we cube both numbers we get 1,000,000,000m3 in a km3. Therefore, to convert from km3 to m3 you have to multiply the number you have by 1,000,000,000.

10^18 or a quintillion.

There are 1000 liters in 1 m3.

It all depends upon the density of the substance. For 1 Kg of Mercury, with a density of 13534 Kg/m3 it will occupy a volume of about 0.0000739 m3. For 1 Kg of Hydrogen with a density of 0.0899 kg/m3 it will occupy a volume of about 11.12 m3.

I don't know. That's what I'm trying to figure out you ideot.

Volume = 4/3*pi*r3 = 4*3*pi*63713 km3 = 1,083,206,000,000 km3 = 1.083 206*1012 km3 Density = 5450 kg/m3 Density = 5450*109 kg/km3 Density = 5.45*1012 kg/km3 So Mass = Density*Volume = 1.083*1012 *5.45*1012 = 5.903*1024 kg. Greater "precision" in the figures would be spurious since the earth is not a perfect sphere

millimetres, centimetres, metres and kilometres cubed or mm3, cm3, m3 and km3

It depends on the amount. Very little: mm3 Drinking Glass: cm3 Pools: m3 Oceans: km3

Earth's surface area is about 510,000,000 km2 or 510,000,000,000,000 m2. 1 mm = 0,001 meter, so the volume is 510,000,000,000,000 m2 * 0,001 m = 510,000,000,000 m3. 1 m3 = 1000 liter so 510,000,000,000 m3 = 510,000,000,000,000 liters or 510 trillion liters (or teralitres). Another way to put it is that 1 mm per m2 is 1 liter per m2 and you have the area above. 510 teralitres is 510 km3 and that is a little bit more than Lake Erie (480 km3).

Water volume Lake Erie = 116 cu mi (480 km3) Lake Huron = 849 cu mi (3,540 km3) Lake Michigan = 1,180 cu mi (4,900 km3) Lake Ontario = 393 cu mi (1,640 km3) Lake Superior = 2,900 cu mi (12,000 km3)

Mercury's volume = 0.056 x Earths (6.08x1010 km3) Venus' volume = 0.857 x Earths (9.38x1011 km3) (Earth) volume = 1 x Earths (1.08x1012 km3) Mars' volume = 0.151 x Earths (1.63x1011 km3) Jupiter's volume = 1321.3 x Earths (1.43x1015 km3) Saturn's volume = 763.59 x Earths (8.2713x1014 km3) Uranus' volume = 63.086 x Earths (6.833x1013 km3) Neptune's volume = 57.74 x Earths (6.254x1013 km3)
