Question

AQUARIUMS An aquarium is 8 feet long, 5 feet wide, and 5.5 feet deep. What is the volume of the tank?

Step-by-Step Solution

Answer

The volume of the aquarium is 220 cubic feet.

Step 1. State the formula.

The formula of volume of a rectangular prism is $V=whl$, where V is the volume, w is the width, h is the height and l is the length of the prism.

Step 2. List the given data.

An aquarium is 8 feet long, 5 feet wide, and 5.5 feet deep.

Then, $l=8\mathrm{ft}$, $w=5\mathrm{ft}$ and $h=5.5\mathrm{ft}$.

Step 3. Calculate the volume.

The shape of an aquarium is that of a rectangular prism.

Put $l=8$, $w=5$ and $h=5.5$ in $V=whl$ to get,

$$\begin{gathered} V=5\times 5.5\times 8 \\ =220 \end{gathered}$$

So, $V=220$.

Step 4. Determine the unit.

Since the units of length, width and height are all given as feet, the unit of volume must be cubic feet.

 

So, the volume of the aquarium is 220 cubic feet.
