Question

Если во время уборки урожая ставить неубранную по три колоска пшеницы на каждом участке площадью 1 м в квадрате это сколько тонн зерна потеряет хозяйстве с участка площадью 625 гектаров в каждом классе имеется 45 г масса 100 зерн равна 40 грамм

Answer 1

1га=10 000м2
1) 625*10000=6 250 000(м2)- площадь участка
2) 6 250 000*3*45=843 750 000(зер.)-на всем участке
3) 843 750 000:100*40=337 500 000(г)=337т500г - потери урожая

Answer 2

Calculating Grain Loss During Harvest

To calculate the grain loss during harvest, we can use the given information: - 3 wheat spikes per square meter - 625 hectares of land - Each spike weighs 45 grams - The weight of 100 grains is 40 grams

First, let's calculate the total weight of the wheat spikes per hectare.

Weight of 3 wheat spikes per square meter: 1. Calculate the weight of 3 wheat spikes per square meter: 3 spikes * 45 grams = 135 grams

Total weight of wheat spikes per hectare: 2. Convert the weight to kilograms: 135 grams = 0.135 kilograms 3. Calculate the total weight per hectare: 0.135 kg/m² * 10000 m² = 1350 kg/ha

Now, let's calculate the total number of grains per hectare and the weight of the grains.

Number of grains per hectare: 4. Calculate the number of spikes per hectare: 3 spikes/m² * 10000 m² = 30000 spikes/ha 5. Calculate the number of grains per hectare: 30000 spikes/ha * 100 grains/spike = 3,000,000 grains/ha

Total weight of the grains per hectare: 6. Calculate the weight of the grains: 3,000,000 grains/ha * 40 grams/grain = 120,000,000 grams 7. Convert the weight to tons: 120,000,000 grams = 120,000 kilograms = 120 tons

Conclusion

By placing 3 unharvested wheat spikes on each square meter, the farm would lose approximately 120 tons of grain from a 625-hectare plot.
