It might have been possible to answer the question if you could be bothered to give some information about the structures. But without that, there can be no answer.
Millimeter centimeter meter kilometer is the right order
0.000016 km, and the answer is not a joke - it is exactly correct.
So far 62 have been discovered, the smallest only a fraction of a kilometer across.
1 cm = 10 mm, so 1 cm2 = 100 mm2 Technically, the correct answer is 10, because the question asks about centimeter square and millimeters square, not square cenitimeter and square millimeters.
The abbreviation of kilometer is km
millimeter is mm, but i assume you mean milliliter, which is mL.
About 1 kilometer away from our home is not a correct grammar.
Smallest is the correct spelling.
The correct spelling is "centimeter".
The phrase "10 times smaller" is grammatically nonsensical, or more accurately, it doesn't really mean what people think it means. 10 times a centimeter is 10 centimeters, so to be 10 times smaller than 1 centimeter would be -9 centimeters 1cm - (10 x 1cm) = -9 centimeters. The more correct way to ask the question is (at least, this is what people usually mean when they say "X times smaller"), "What distance is 1/10th the size of a centimeter?" To which the answer is 1 millimeter. 1 centimeter is 1/100th of a meter (1 cent of a meter). 1 millimeter is 1/1000th of a meter.
yes, you are correct
