Answer:

\text{Volume}=30\text{ ft}^3

Step-by-step explanation:

We have been given that the density of a fish tank is \frac{0.4\text{ fish}}{\text{ ft}^3}. There are 12 fish in the tank.

To find the volume of the tank we will use density formula.    

\text{Density}=\frac{\text{Mass}}{\text{Volume}}

Upon substituting our given values in above formula we will get,

\frac{0.4\text{ fish}}{\text{ ft}^3}=\frac{12}{\text{Volume}}

Cross multiplying our equation we will get,

0.4\text{ fish}*\text{Volume}=12\text{ fish}*\text{ ft}^3

\frac{0.4\text{ fish}*\text{Volume}}{0.4\text{ fish}}=\frac{12\text{ fish}*\text{ ft}^3}{0.4\text{ fish}}

\text{Volume}=\frac{12\text{ ft}^3}{0.4}

\text{Volume}=30\text{ ft}^3

Therefore, the volume of the fish tank is 30 cubic feet.

Answer: 30\ ft.^3

Step-by-step explanation:

Given: Density of tank = 0.4 fish over feet cubed.

We know that, \text{Density}=\frac{\text{Mass}}{\text{Volume}}

Therefore,

\text{Volume of the tank}=\frac{\text{Mass}}{\text{Density}}\\\\\Rightarrow\ \text{Volume of the tank}=\frac{12}{0.4}\\\\\Rightarrow\ \text{Volume of the tank}=30\ ft.^3

Hence, the volume of the tank = 30\ ft.^3

How do you express your terms in pi
il63 [147K]

Answer:

To express your answer in terms of pi, simply refrain from substituting pi's numerical value for its symbol in the equation. That way, your answer will look like xπ where x is whatever number you come up with, and π is simply a placeholder.
