    Answer:

    9\times 10^{10}” or “90000000000” grains are there in 6300 kg of sand

    Step-by-step explanation:

    Given

    1 grain sand weighs = 7\times 10^{-5}

    Let x be the number of grain in 6300 kg of sand

    Solution:

    x= \frac{6300 \times 10^3}{7\times10^{-5}}= 900\times10^3\times10^5=9\times10^{10}

    9\times 10^{10}” or “90000000000” grains are there in 6300 kg of sand
