Question

1) A box has a mass of 8 kg and a volume of 2 m? What is its density? |

Answer 1

`\huge\boxed{4\ \text{kg/m$^3$}}`

We know that
`\rho=m/ V`, where
`\rho` is density,
`m` is mass, and
`V` is volume.

Substitute in the values we know and solve:

`\begin{aligned}\rho&=8/2\\&=\boxed{4}\end{aligned}`
