Question

У Андрея два аквариума. Длина , ширина и высота одного из них 9/10 м , 2/5 м и 1/2 м , а другого-4/5 м , 3/4 м и 3/10 м. В какой из аквариумов вмещается больше воды? Помогите пожалуйста!) дам 13 баллов

Answer 1

V = a * b * c - формула объёма
--------------------------------------------
1) 9/10 * 2/5 * 1/2 = (9*2*1)/(10*5*2) = 9/50 (куб.м) - объём одного аквариума;
2) 4/5 * 3/4 * 3/10 = (4*3*3)/(5*4*10) = 9/50 (куб.м) - объём другого аквариума;
3) 9/50 = 9/50 - объёмы двух аквариумов равны.
Ответ: одинаково. 

Answer 2

V1=abh=9/10*2/5*1/2=(9*2*1)/(10*5*2)=18/100=9/50 куб м
V2=abh=4/5*3/4*3/10=(4*3*3)/(5*4*10)=36/200=18/100=9/50 куб м
Аквариумы одинаковы по объему.

Answer 3

Calculation of Water Volume in Each Aquarium

To determine which aquarium can hold more water, we need to calculate the volume of water in each aquarium. The volume of a rectangular prism, such as an aquarium, is calculated by multiplying its length, width, and height.

Let's calculate the volume of water in each aquarium:

1. First Aquarium: - Length: 9/10 m - Width: 2/5 m - Height: 1/2 m

To calculate the volume, we multiply the length, width, and height:

Volume of the first aquarium = (9/10) m * (2/5) m * (1/2) m

2. Second Aquarium: - Length: 4/5 m - Width: 3/4 m - Height: 3/10 m

To calculate the volume, we multiply the length, width, and height:

Volume of the second aquarium = (4/5) m * (3/4) m * (3/10) m

Comparing the Volumes of the Aquariums

Now that we have calculated the volumes of water in each aquarium, let's compare them to determine which aquarium can hold more water.

To compare the volumes, we can simply compare the calculated values.

- Volume of the first aquarium: (9/10) m * (2/5) m * (1/2) m = 0.18 cubic meters - Volume of the second aquarium: (4/5) m * (3/4) m * (3/10) m = 0.225 cubic meters

From the calculations, we can see that the second aquarium can hold more water, with a volume of 0.225 cubic meters, compared to the first aquarium, which has a volume of 0.18 cubic meters.

Therefore, the second aquarium can hold more water than the first aquarium.

I hope this helps! Let me know if you have any further questions.
