Answer: (b) maximum when breadth and width form the base
Pressure is defined as the ratio of force to cross-section area.
Pressure(P) = Force(F)/Area(A)
Pressure will be maximum when the area will be minimum.
- Length = 60cm
- Breadth = 40cm
- Width = 20cm
Area of the base formed by length and breadth = 60 × 40 = 2400 cm²
Area of the base formed by breadth and width = 40 × 20 = 800 cm²
Area of the base formed by width and length = 20 × 60 = 1200cm²
∴ Area of the base formed by breadth and width is minimum so, pressure will be maximum.
