Question

Для определения количества выпавших осадков на клумбу длиной 7 м и шириной 3 м установили ведро с прямыми боками. После дождя уровень воды в ведре стал равен 8 см. Сколько литров воды выпало на клумбу? Ответы: А.1570 л; В. 1680 л; С. 1600 л; Д. 1720 л.

Answer 1

Дано:
А=7м
В=3м
С=8см
Найти: V-? (Объём)
Решение:
Так как уровень воды был такой же как и в ведре, то ищем объём, переведя в дм куб
70*30*0,8=1680 литров
Ответ:1680 литров

Answer 2

Calculation of Rainfall on the Flower Bed

To determine the amount of rainfall that fell on the flower bed, we can use the information provided. The flower bed has a length of 7 meters and a width of 3 meters. A bucket with straight sides was placed on the flower bed, and after the rain, the water level in the bucket was measured to be 8 centimeters.

To calculate the volume of water that fell on the flower bed, we need to convert the measurements to the same unit. Let's convert the length, width, and water level to meters:

- Length of the flower bed: 7 meters - Width of the flower bed: 3 meters - Water level in the bucket: 8 centimeters = 0.08 meters

Now, we can calculate the volume of water that fell on the flower bed using the formula:

Volume = Length x Width x Height

Substituting the values:

Volume = 7 meters x 3 meters x 0.08 meters

Calculating the volume:

Volume = 1.68 cubic meters

Therefore, the amount of water that fell on the flower bed is 1.68 cubic meters.

However, the question asks for the volume in liters. To convert cubic meters to liters, we can use the conversion factor:

1 cubic meter = 1000 liters

Converting the volume:

1.68 cubic meters x 1000 liters/cubic meter = 1680 liters

Therefore, the answer is В. 1680 литров.
