A granary in the Indus Valley stored 800 kg of wheat. If the average weight of a wheat grain is 0.6 g, how many grains of wheat does the granary contain? Round to the nearest whole number.

Step-by-step solution

1. Convert 800 kg to grams: $800\times 10^3\text{ g}=800000\text{ g}$.
2. Divide by the weight of one grain: $\frac{800000\text{ g}}{0.6\text{ g}}=1333333.\overline{3}$.
3. Round to the nearest whole number to get $1333333$ grains.
