Question

Высота аквариума 2 дм, а водой он наполнен до высоты 15 см.сколько литров воды ещё можно влить в аквариум, если два других измерения аквариума 8дм и 2дм.

Answer 1

2 * 2 * 8 = 32 дм³ - объём аквариума.
15 см = 1,5 дм
2 * 8 * 1,5 дм = 24 дм³ заполнены водой.
32 - 24 = 8 дм³ = 8 л - можно долить.

Answer 2

Calculation of the Volume of the Aquarium

To calculate the volume of the aquarium, we need to multiply the three dimensions together: length, width, and height. In this case, the length is 8 dm, the width is 2 dm, and the height is 2 dm.

The formula for calculating the volume of a rectangular prism is:

Volume = Length x Width x Height

Substituting the given values into the formula, we get:

Volume = 8 dm x 2 dm x 2 dm

To simplify the calculation, we can convert the dimensions from decimeters (dm) to centimeters (cm) since 1 dm is equal to 10 cm.

Volume = 80 cm x 20 cm x 20 cm

Now, let's calculate the volume:

Volume = 32,000 cm³

Calculation of the Remaining Water Capacity

To calculate the remaining water capacity, we need to subtract the volume of water already in the aquarium from the total volume of the aquarium.

The height of the water in the aquarium is given as 15 cm. We can calculate the volume of water using the formula:

Volume of Water = Length x Width x Height of Water

Substituting the given values into the formula, we get:

Volume of Water = 8 dm x 2 dm x 15 cm

Converting the dimensions to centimeters:

Volume of Water = 80 cm x 20 cm x 15 cm

Now, let's calculate the volume of water:

Volume of Water = 24,000 cm³

To find the remaining water capacity, we subtract the volume of water from the total volume of the aquarium:

Remaining Water Capacity = Total Volume - Volume of Water

Remaining Water Capacity = 32,000 cm³ - 24,000 cm³

Remaining Water Capacity = 8,000 cm³

Therefore, there is still 8,000 cm³ (or 8 liters) of water that can be poured into the aquarium.
