Answer 2

Calculation of the Number of Fish in an Aquarium

To calculate the number of fish that can be kept in an aquarium, we need to consider the volume of the aquarium and the space required for each fish.

Given the dimensions of the aquarium: - Length: 50 cm - Width: 30 cm - Height: 25 cm

And the requirement of 2 liters of water per fish, we can calculate the volume of the aquarium in liters.

Calculation:

The volume of the aquarium can be calculated by multiplying the length, width, and height:

Volume = Length x Width x Height

Converting the dimensions to liters, we can use the conversion factor of 1 liter = 1 cubic decimeter (dm³):

Volume (in liters) = Volume (in cubic decimeters)

Now, let's calculate the volume of the aquarium:

Volume = 50 cm x 30 cm x 25 cm = 37,500 cm³

Converting cm³ to liters:

Volume (in liters) = 37,500 cm³ ÷ 1,000 = 37.5 liters

Therefore, the volume of the aquarium is 37.5 liters.

To determine the number of fish that can be kept in the aquarium, we divide the volume of the aquarium by the water requirement per fish:

Number of fish = Volume of the aquarium ÷ Water requirement per fish

Number of fish = 37.5 liters ÷ 2 liters = 18.75

Since we cannot have a fraction of a fish, we round down to the nearest whole number.

Therefore, you can keep 18 fish in the given aquarium.

Please note that this calculation assumes that each fish requires exactly 2 liters of water and does not take into account other factors such as the size and species of the fish, filtration system, and other requirements for fish health and well-being. It is always important to research and consider the specific needs of the fish species you plan to keep in an aquarium.
