Question

В пустой аквариум, длина которого равна 80 см,а ширина-40 см, налили 18 вёдер воды, в каждом из которых было 10 л воды. Определите расстояние от поверхности воды до дна аквариума. В первом действии надо найти площадь дна аквариума, а во втором объём налитой воды!!!

Answer 1

1) 80 * 40 = 3200(кв.см) - площадь дна аквариума
2) 10 * 18 = 180(л) = 180(куб.дм) = 180000(куб.см)  - объём налитой воды
3) 180000 : 3200 = 56,25(см)
Ответ: 56,25 см - расстояние от поверхности воды до дна аквариума.

Answer 2

Calculation of the Area of the Aquarium's Bottom

To determine the distance from the surface of the water to the bottom of the aquarium, we first need to calculate the area of the aquarium's bottom. The length of the aquarium is given as 80 cm, and the width is given as 40 cm.

To find the area of the bottom, we can use the formula:

Area = Length x Width

Substituting the given values:

Area = 80 cm x 40 cm

Calculating the area:

Area = 3200 cm²

Calculation of the Volume of Water

Next, we need to calculate the volume of water that has been poured into the aquarium. It is mentioned that 18 buckets of water were poured, with each bucket containing 10 liters of water.

To find the volume of water, we can use the formula:

Volume = Number of Buckets x Volume per Bucket

Substituting the given values:

Volume = 18 buckets x 10 liters/bucket

Calculating the volume:

Volume = 180 liters

Determining the Distance from the Surface to the Bottom

To determine the distance from the surface of the water to the bottom of the aquarium, we need to divide the volume of water by the area of the bottom. This will give us the height or depth of the water in the aquarium.

Using the formula:

Height = Volume / Area

Substituting the calculated values:

Height = 180 liters / 3200 cm²

Calculating the height:

Height ≈ 0.05625 cm

Therefore, the distance from the surface of the water to the bottom of the aquarium is approximately 0.05625 cm.
