Diketahui:

Satuan $m=\text{kg}$

Satuan $t=\text{s}$

Satuan $v=\text{m/s}$

Satuan $x=\text{m}$

Ditanyakan:

Satuan $\left(\frac{m}{x^3}\right)\frac{v}{t}\ x$ $\ =...$

Jawab:

$\left(\frac{m}{x^3}\right)\frac{v}{t}\ x=\left(\frac{\text{kg}}{\text{m}^3}\right)\frac{\text{m/s}}{\text{s}}\text{m}$

$=\left(\frac{\text{kg}}{\text{m}^3}\right)\frac{\text{m}^2}{\text{s}^2}$

$=\frac{\text{kg}}{\text{ms}^2}$

Jadi, satuan $\left(\frac{m}{x^3}\right)\frac{v}{t}\ x$ adalah $\text{kg/ms}^2$
