# Taking Force, Length and Time to Be the Fundamental Quantities, Find the Dimensions of Pressure . - Physics

Sum

Taking force, length and time to be the fundamental quantities, find the dimensions of pressure .

#### Solution

Pressure
$= \frac{\text{ force}}{\text{area}}$

$\left[ \text{ Area }\right] = \left[ L^2 \right]$
$\therefore \left[\text{ Pressure }\right] = \frac{\left[ F \right]}{\left[ L^2 \right]} = \left[ {FL}^{- 2} \right]$

Is there an error in this question or solution?
