Question

The pressure exerted by the cubical block of side 3cm on the surface is 5Pa.Calculate the force of the block.

Answer 1

Explanation:

side = 3cm

area = 3×3=9cm sq.

pressure = 5 Pa

force = pressure ×area

= 5×9

= 45 N

therefore, the force is of 45 N.

Answer 2

Answer:

F=A×P

Area= side 3cm, S×S = 3×3 = 9cm²

Pressure = 5pa

Force = A×P = 9cm×5pa = 45N
