Question

Длина улицы 800 м , а ширина 15 м . Улицу покрыли асфальтом . На каждую 100 м (квадратных)нужно 3 тонны асфальта . Сколько всего тонн асфальта использывали на покрытия улицы ?

Answer 1

800×15=12000м(квадратных)
12000:100=120 по три тонны
120×3=360тонн асфальта
ответ360 тонн

Answer 2

Calculation of Asphalt Quantity

To calculate the total amount of asphalt used to cover the street, we need to determine the area of the street and the amount of asphalt required per square meter.

Given: - Length of the street: 800 m - Width of the street: 15 m - Amount of asphalt required per 100 square meters: 3 tons

To find the area of the street, we can multiply the length by the width:

Area of the street = Length × Width = 800 m × 15 m = 12,000 square meters

Now, we need to calculate the number of 100 square meter sections in the total area of the street. We can divide the total area by 100:

Number of 100 square meter sections = Area of the street / 100 = 12,000 square meters / 100 = 120 sections

Since each 100 square meter section requires 3 tons of asphalt, we can multiply the number of sections by the amount of asphalt required per section:

Total amount of asphalt = Number of sections × Amount of asphalt per section = 120 sections × 3 tons = 360 tons

Therefore, a total of 360 tons of asphalt were used to cover the street.
