Question

the density of a fish tank is 0.2 fish over feet cubed. There are 8 fish in the tank. What is the volume of the tank? a. 4ft cubed b. 16ft cubed c. 32 ft cubed or d. 40 ft cubed

Answer 1

Density is a physical property which describes the mass of a substance per unit of volume of the substance. It is expressed as Density = m / V and it has units like g/cm^3. We use the density given to solve the problem.
Volume of the tank = 8 fishes / 0.2 fish / ft³
The volume of the tank = 40 ft³

Answer 2

Option d

Explanation:

We are given that the density of fish tank =0.2 fish over feet cubed

We have to find the volume of fish tank

To find the volume of fish tank we are using density formula

`Density=(mass)/(volume)`

Total number of fish =8

Substitute the value the we get

0.2=
`(8)/(V)`

By cross multilply we get

0.2 V=8

Using division property of equality then we get

`V=(8)/(0.2)`

V=
`(80)/(2)=40` feet cubed

Hence, option d is true.
