Question

Резервуар имеет форму прямоугольного параллелепипеда с размерами 3м,1м и 4дм.Сколько 12-литровых вёдер воды надо принести, чтобы его заполнить?

Answer 1

30дм*10дм*4дм=1200дм3
12л=12дм3
1200дм3/12дм3=100 вёдер

Answer 2

Calculation of the Volume of the Reservoir

To determine the number of 12-liter buckets of water needed to fill the reservoir, we first need to calculate the volume of the reservoir. The reservoir is in the shape of a rectangular parallelepiped with dimensions of 3 meters, 1 meter, and 4 decimeters.

To calculate the volume of a rectangular parallelepiped, we multiply its length, width, and height. In this case, the length is 3 meters, the width is 1 meter, and the height is 4 decimeters.

However, we need to convert the height from decimeters to meters to ensure consistent units. Since 1 decimeter is equal to 0.1 meters, the height of the reservoir is 4 decimeters * 0.1 meters/decimeter = 0.4 meters.

Now we can calculate the volume of the reservoir:

Volume = length * width * height Volume = 3 meters * 1 meter * 0.4 meters Volume = 1.2 cubic meters

Calculation of the Number of 12-Liter Buckets

To calculate the number of 12-liter buckets needed to fill the reservoir, we divide the volume of the reservoir by the capacity of each bucket.

Number of buckets = Volume of reservoir / Capacity of each bucket Number of buckets = 1.2 cubic meters / 12 liters

However, we need to convert the volume of the reservoir from cubic meters to liters to ensure consistent units. Since 1 cubic meter is equal to 1000 liters, the volume of the reservoir is 1.2 cubic meters * 1000 liters/cubic meter = 1200 liters.

Now we can calculate the number of 12-liter buckets needed:

Number of buckets = 1200 liters / 12 liters Number of buckets = 100 buckets

Therefore, you would need to bring 100 12-liter buckets of water to fill the reservoir.

Note: It's important to double-check the accuracy of the calculations and measurements to ensure the desired result.
