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 $\rho=m\div V$, where $\rho$ is density, $m$ is mass, and $V$ is volume.

Substitute in the values we know and solve:

$\begin{aligned}\rho&=8\div2\\&=\boxed{4}\end{aligned}$
