Calculate the Patm And the pressure exerted by water on the block

- The area Of the upper face of block is 40 cm2 Calculate the total pressure exerted on the solid

Given : In the first tube : in a tube a solid .. the height from solid to the water level in the tube is 8o cm

& in the 2nd tube the height of the solid on the surface of water is 75 cm ( the height of the solid above water )
