Question

A 60-kg woman stands on a light cubical box with each side measured as 20 cm. The box sits on the floor. What is the pressure exerted by the box on floor? (assume the box is too light to be counted for)

Answer 1

force exerted by the cubical box with woman on the floor , $60\times 9.8=588$ N

area of cubic surface attached with the floor,  $0.2\times 0.2=0.04 M^{2}$

$\therefore$ pressure exerted,=   

force area

   =    $\frac{588}{0.04}= 587.96 \frac{N}{M^{2}}$
