Given the statement: One grain of sand approximately weighs 7 * 10^{-5} g.
To find how many grains of sand are there in 6300 kg of sand.
Let x be the number of grains of sand in 6300 kg of sand.
Using conversion :
1 kg = 1000 g
6300 kg = 6300000 g
Then, by using proportion method, we have;
By cross multiply we get;
or
[using 
]
Divide both sides by 7 we get;
Standard form is a way of of writing down very large or very small numbers easily.
Therefore, 
grains of sand are there in 6300 kg of sand.
