33. 18

34. = 2 x 13= 5 + 6 + 7 + 8

There are 26 letters in the English alphabet.

Precipitevolissimevolmente with 26 letters is the longest word in the Italian language. It means `as fast as possible'.

I think flauccipausinihiliplification is the longest word in English language (meaning: the art of estimating something as worthless) or anthidisestablishmentarianism. However, the names of some chemicals are even longer.

Devante`,

your reply to 33 is correct.

But the answer to 34 is 26 is the only number in the universe jammed between a square (25) and a cube (27). I don't know if there's any proof availabe for this fact, I have tried searching the internet and the results don't give any proof.

What has that got to do with the question?

BTW, it's not the longest word.

You are correct, Devante`.

Its got nothing to do with the question.

As I mentioned earlier, certain chemical names are much larger than the words we talked about earlier.

Light travels from the sun to here in 8 minutes, 20 seconds, so that means that it's:

((8*60)+20)*3*10^5 km away from us, which is 1.5*10^8 km away from us. Roughly.

Ooh, and 1729 can be written as a sum of cubes in 2 different ways. I noticed that 729 = 9^3 and worked it out from there.

Why did the vector cross the road?

It wanted to be normal.

The distance between the Earth and the Sun is 93,000,000 Miles...rounded.

I knew that as a fact.

729+1000 = 9³+10³ = 1729 - Both integers with powers are consecutive.

I was saying that 1729 was special because that was one of 2 cube-sums it could have.

1729 = 10³+9³ = 12³+1³. And that's most probably the first number that can do that.

Yes, mathsyperson and Devante'. You are correct.

The sun is 499 light seconds away from earth. Light travels at 3x10^8 metres per second. Therefore sun is roughly 1.5 x 10^8 kilometers away.

37. 1024 - But sometimes referred to as 1000.

38. 1 floppy = 1.44 MB

1.44 MB x 3.5 = 5.09 MB

Memory of a 3 1/2 floppy: 5.09 MB

Devante`,

Your answer to #37 is correct.

#38 is correct too. But 3 1/2 inch floppy is 1.44 MB. You

need not have multiplied it by 3.5.

Justlookingforthemoment, both the words you have givesn are the longest in English language if some chemical names are not taken into account.

39. If 220 yards make a furlong and 8 furlongs make a mile, how many yards is a mile?

Devante`, very very well done

40. Approximately how many stars can be seen in the sky on a clear night sky?

41. Approximately how many strands of hair are there on a normal man's head?

42. If a polyhedron contains 12 vertices and 8 sides, how many edges would it contain?

40. No idea, I was never taught that

41. 100000, I think. Don't remember if that applies to a specific gender

42. I'll come back to

I have no idea about the starry sky one either. I'd estimate around 1000000. I'm probably completely wrong.

I think the number of hairs thing depends on hair colour, as well as gender. If I remember, blondes have more hair than black-haired people and black-haired people have more hair than redheads. I think the average is around 60000.

And I know for certain that your polyhedron has 18 edges. Thankyou, Euler.
