Question

Площадь длиной 800 м шириной 500 м покрыли асфальтом. на каждые 100 кв. м расходовали 3т 800 кг асфальта. Сколько тонн асфальта израсходовали?

Answer 1

1) 800*500=400000(кв.м)-вся площадь покрытая асфальтом

2) 400000/100=4000(кол-во)-площадей по 100 кв.м

3) 4000*3800=15200000(кг)-асфальта понадобится для покрытия

4) 15200000кг=15200т

Answer 2

1)3800:100=38(т.) - ихрасходывали на 1 кв. М

2)500×800=400000(см кв.) площадь

3)400000×38=15200000

Answer 3

Calculation of Asphalt Consumption

To calculate the amount of asphalt that was used to cover an area with a length of 800 meters and a width of 500 meters, we need to find the total area and then determine the asphalt consumption per square meter.

The total area can be calculated by multiplying the length and width of the area:

Total Area = Length x Width

Total Area = 800 m x 500 m

Total Area = 400,000 square meters

Next, we need to determine the asphalt consumption per square meter. According to the given information, for every 100 square meters, 3,800 kilograms of asphalt were used.

To find the asphalt consumption per square meter, we can divide the asphalt consumption per 100 square meters by 100:

Asphalt Consumption per Square Meter = Asphalt Consumption per 100 Square Meters / 100

Asphalt Consumption per Square Meter = 3,800 kg / 100

Asphalt Consumption per Square Meter = 38 kg

Now, we can calculate the total amount of asphalt used by multiplying the asphalt consumption per square meter by the total area:

Total Asphalt Consumption = Asphalt Consumption per Square Meter x Total Area

Total Asphalt Consumption = 38 kg/m² x 400,000 m²

Total Asphalt Consumption = 15,200,000 kg

Therefore, 15,200,000 kilograms of asphalt were used to cover an area with a length of 800 meters and a width of 500 meters.
