Question

What is the width of a rectangular prism if the volume = `80` `i``n^3`, the height is `2` `i``n`, and the length is `8` `i``n`?

Answer 1

`5i` `n`

Explanation:

`V_"rectangular prism"=lhw`

We know that `80=8(2)w`.

We can simplify this by multiplying `8` and `2` to get that `80=16w`.

Finally, we can divide both sides by `16` to find that `w=5`, so the width of the rectangular prism is `5i` `n`.
