**gadzooksseans rolled a random image posted in comment #284 at Police Troll ** i can barely get through captcha math... please don't make me do this
exam:
If Tommy has three apples and Sally takes two...calculate the mass of the sun.
asian: well 3 apples mass is about 1/2 a kg so 2 would be 1/3kg and the sun is 1300000times larger than the earth and we know that an apple is about 3.5cm in radius and the earth is about 6370km in radius if I remember correctly. so we then find the volume of an apple is 0.00000000000018 km^3 and the earth is 1,080,000,000,000km^3 and we find that 6,013,551,202,539,252,336,923 apples will fit in the earth so 7,817,616,563,301,028,038,000,447,300,000 will fit in the sun and the sun's density is about 1.58 times that of an apple which gives us the sun is approximately 2,000,000,000,000,000,000,000,000,000,000kg rounded to the nearest nonillion.

Idk who ripped who off but this content showed up on shitty site we should ignore around the same time this was posted.
that awkward moment when the majority of top funnyjunk comments are: in this thread, racist, hilarious.

To do so one must identify and understand a few givens (said to be constants for a logical solution to this equation)
1. Mass = Density*Volume
2. sun is a perfect sphere(assumption, not exactly true)
3. sun is composed of hydrogen( mostly, im not going to get into advanced thermocompositions of stars)
4. Density of sun ≈ 1.4 g/cm3 (mean density)
5.Volume of sun ≈ 1.412×1018 km3
Therefore mass of sun ≈ (1.412×1018 km3)*(1.4 g/cm3)
bring it on, schoolRon Paul haters

That is asuming that gasses are not compressable which they are. So even though the sun is made of hydrogen its average density is far far greater due to an increase in density the farther into the sun you go. So you are way off on your calculations. That and you didn't even convert the density to grams/km^3 so your answer is off there again. In summery you fail at science, and get a B in math.
heh... google it. I did use a mean density. 1.4 g/cm3 is more dense than water @ 1.0 g/cm......where the hydrogen burns @ a plasma state on the outer reaches of the sun it is considerably less dense. 1.4 g/cm3 is generally accepted as the standard mean density of the sun, which is fairly dense considering the sun is made up of pretty much the two lightest gasses known, (hydrogen and helium). And really? you are going to try and correct formatting? It is just conversions of 1,000. Also commonly known facts. Basically in an effort to answer this question for the common man I made basic assumptions necessary for the solving of a finite equation in a static scenario. Because the sun is constantly expanding and contracting in various cycles and as foreign matter is burnt, of course there are counter arguments to be made here, but in order to do the maths involved, you have to take it at a single moment in time to receive one single answer.
yep that was my mistake, i assumed the density would be greater due to internal gravity but I just ran the numbers myself using centipital force and gravitation equations and I got the same mass of the sun as listed on google. My bad good sir, please continue.
