Question

аквариум необходимо заполнить водой . сколько ведер потребуется, если в ведро входит 10 кг воды, а размеры аквариума таковы: длина 1 м,ширина 0,5м, а уровень воды в нём должен быть 70 см

Answer 1

Дано:

l=1 м

k=0.5 м

h=0,7 м

m1=10 кг

n=? число ведер

Решение:

Для воды 1кг=1л, тогда в одном ведре V1=10 л

V2=l*k*h=1*0,5*0,7=0,35 м3 = 350 л

n=V2:V1=350:10=35

Ответ: потребуется 35 ведер.

 

 

Answer 2

Calculation of the Number of Buckets Required to Fill the Aquarium with Water

To calculate the number of buckets required to fill the aquarium with water, we need to determine the volume of the aquarium and the volume of water that each bucket can hold.

The volume of the aquarium can be calculated by multiplying its length, width, and height. In this case, the length is 1 meter, the width is 0.5 meters, and the desired water level is 70 centimeters.

To convert the dimensions to meters, we divide the width and water level by 100:

- Length: 1 meter - Width: 0.5 meter (0.5 / 100 = 0.005 meters) - Water level: 0.7 meter (70 / 100 = 0.7 meters)

The volume of the aquarium is then calculated as follows:

Volume of the aquarium = Length x Width x Water level

Volume of the aquarium = 1 meter x 0.005 meter x 0.7 meter

Volume of the aquarium = 0.0035 cubic meters

Now, let's determine the volume of water that each bucket can hold. According to the information provided, each bucket can hold 10 kilograms of water.

To convert the weight of water to volume, we need to know its density. The density of water is approximately 1 kilogram per liter, or 1000 kilograms per cubic meter.

Therefore, the volume of water that each bucket can hold is calculated as follows:

Volume of water per bucket = Weight of water per bucket / Density of water

Volume of water per bucket = 10 kilograms / 1000 kilograms per cubic meter

Volume of water per bucket = 0.01 cubic meters

Finally, we can calculate the number of buckets required to fill the aquarium by dividing the volume of the aquarium by the volume of water per bucket:

Number of buckets required = Volume of the aquarium / Volume of water per bucket

Number of buckets required = 0.0035 cubic meters / 0.01 cubic meters

Number of buckets required = 0.35 buckets

Therefore, approximately 0.35 buckets of water will be required to fill the aquarium to a water level of 70 centimeters.

Please note that since buckets are typically sold in whole numbers, you would need to round up to the nearest whole number. In this case, you would need at least 1 bucket to fill the aquarium.
