Answer:
"[tex]9\times 10^{10}[/tex]" or "90000000000" grains are there in 6300 kg of sand
Step-by-step explanation:
Given
1 grain sand weighs = 7[tex]\times[/tex] [tex]10^{-5}[/tex]
Let x be the number of grain in 6300 kg of sand
Solution:
x= [tex]\frac{6300 \times 10^3}{7\times10^{-5}}= 900\times10^3\times10^5=9\times10^{10}[/tex]
"[tex]9\times 10^{10}[/tex]" or "90000000000" grains are there in 6300 kg of sand
