Question

the pressure exerted by a cube of side 0.03mon a surface is 10pa. calculate the thurst exerted by the cube

Answer 1

Heya.

This is your answer.

GIVEN :-
Side of cube = 0.03 m 
Hence, area = 0.03 X 0.03 = 0.0009 m².     (as area of cube is side²)

Pressure = 10 Pa.

As we know that thrust is force acting per unit area.
So, thrust = force.
and force = pressure X area
So, 
= 10 X 0.0009
= 0.009 Pa.

Hence, the thrust exerted by the box is 0.009 Pa.
Hope it helps
