Question

A pet store supplier has a special on cube shaped fish tanks. Using the expression for finding volume of a cube V = n^3, determine volume of a cube shaped fish tank with the side n of 4.5 ft.

Answer 1

The volume of the cube is;

`91.125ft^3`

Step-by-step explanation:

Given that the Volume of a cube is;

`V=n^3`

The volume of a cube shaped fish tank with the side n of 4.5ft;

`n=4.5\text{ ft}`

Substituting the value of n;

`\begin{gathered} V=(4.5ft)^3 \\ V=4.5*4.5*4.5ft^3 \\ V=91.125 \\ V=91.125ft^3 \end{gathered}`

Therefore, the volume of the cube is;

`91.125ft^3`
