Solution:

we are given that one grain of sand weighs 7x10^-5 Kg.

There is a total of 6300Kg of sand.

So we will divide the total weight by weight of one grain of sand.

Number of sand
=(6300)/(7*10^(-5))

Number of sand
=(6300*10^(5))/(7)

Number of sand
=900*10^(5)

Hence there are 900x10^5 sands.
