Question

calculate the pressure exerted through each of the faces of a rectangular cuboidal body of mass 25 kg having dimension 40 cm * 25 cm * 15 cm.​

Answer 1

Answer:

1)2450pa (2)6533.33 pa (3) 4083.33pa

Explanation:

Given: Mass=25kg, Dimensions= 40cm,25cm,15cm

To find: The pressure exerted through each of the faces.

Solution: We know acceleration due to gravity is

9.8 m/s²

Now ,Force= 25×9.8 = 245N

Pressure¹=

245N/ (40/100×25/100)m²=2450pa

Pressure²=

245N/(25/100×15/100)m²=6533.33 pa

Pressure³=

245N/(15/100×40/100)m²=4083.33 pa
