how many stars in the universe grains of sand
Now of course, this is just an estimate. There could actually be upwards of 200 sextillion stars in the universe, there just really is no way of saying for sure. But for the purposes of this investigation, 10 sextillion is the magic number used by Mr.Cain, who now moves on to estimate the number of grains of sand on Earth's beaches... Around 8,000 grains of sand can be packed into one cubic centimeter, which according to Mr.Cain means that 10 sextillion grains of sand placed in a ball would create a sphere with a radius of 10.6 kilometers. According to Cain's associate, 'The Math Dude', there are approximately 700 trillion cubic meters of beach on our planet.
