Here is few statement regarding pressure: 1.High building are made on broader base: Larger the area of base: Lesser the pressure on ground. 2.The cutting edge of knives are made very sharp: Lower the area of contact: more the penetration power. 3. Skies have very long and broad flat skies: More the area of contact: Lesser the chances of sinking in ice. Which of the following statement is correct:
