Question

A box has dimensions 15*20*25 cm. Calculate the pressure exerted by the box if mass of box is 20 kg.

Answer 1

Dear Student ,
Here in this case the pressure on the surface with dimension 15 cm and 20 cm is ,
$P_a=\frac{20\times 10}{15\times 20\times {10}^{-4}}=6666·67N/m^2$
Now the pressure on the surface with dimension 20 cm and 25 cm is ,
$P_b=\frac{20\times 10}{25\times 20\times {10}^{-4}}=4000N/m^2$
Now the pressure on the surface with dimension 15 cm and 25 cm is ,
$P_c=\frac{20\times 10}{15\times 25\times {10}^{-4}}=5333·33N/m^2$
