Cabrini's Pet Shop sells aquariums in the shape of a right rectangular prism. Each aquarium measures 50 inches long, 20 inches wide, and 30 inches tall. The recommended density of each aquarium is no greater than 0.002 fish per cubic inch. Based on the recommendation, what is the greatest number of fish that should be in one aquarium?




15 fish


60 fish


600 fish


15,000,000 fish

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

Volume = 50 inches * 20 inches * 30 inches = 30,000 cubic inches

The maximum number of fish that can be in the aquarium is calculated by multiplying the volume of the aquarium by the recommended density of 0.002 fish per cubic inch:

Maximum number of fish = 30,000 cubic inches * 0.002 fish per cubic inch = 60 fish

Therefore, the greatest number of fish that should be in one aquarium is 60 fish.
