Answer:
60 fishes
Explanations:
The length of the aquarium = 50 inches
The width of the aquarium = 20 inches
The height of the aquarium = 30 inches
The aquarium has the shape of a rectangular prism
The volume of a rectangular prism is:
V = Length x width x height
V = 50 x 20 x 30
V = 30000 cubic inches
The density of the aquarium = 0.002 fish per cubic inch
Density = (Number of fishes) / Volume of the aquarium
0.002 = (Number of fishes) / 30000
Number of fishes = 0.002 x 30000
Number of fishes = 60
There can be 60 fishes in one aquarium
