How many grains of sand are in one square inch?
It depends on the kind of sand you're talking about.There are five different types of sand, ranging from very fine to very course. Let's take the middle type of sand, which is medium sand.A grain of medium sand is between 1/50 of an inch and 1/100 of an inch. If you take the middle number between that range (~1/67), then we can estimate that a square inch of sand would have approximately 4500 grains of sand (67 squared is 4,489). This assumes a completely flat layer of sand one grain deep.A cubic inch of such sand would have just over 300,000 grains of sand.Obviously this number will vary based on the type of sand you're working with and can only be used for estimation purposes.IMPROVEMENT:Hmmm, first of all, the "middle number" would seem to be 1/75, not 1/67. Let's take 1/75.Second, the packing could be much denser than what the computation above seems to assume. With a denser packing of the grains of sand, a computation shows a shade less than 600,000 grains of 1/75" sand in a cubic inch.
What would a million grains of sand look like?
A very small sandcastle.
What does VF mean in grading coins?
Very fine condition
In valuing coins what does g vg f vf ef au ms stand for?
G: good VG: very good F: fine VF: very fine EF: extremely fine AU: almost uncirculatedMS: mint condition
This matter has a density of 30 ml and mass of 579g what is it?
You mean a volume of 30 ml and mass of 579 g. Its s density = mass/volume = 579/30 = 19.3 g/ml which is very heavy. It could be several choices, but GOLD is that density...
