Answer:
P_min = 490 N/m²
P_max = 7350 N/m²
Explanation:
Formula for pressure is;
Pressure = Force/Area
We are given;
Mass = 30 kg
Dimensions of Block = 0.1 m by
0.4 m by 1.5 m.
Force(weight) = mg = 30 × 9.8 = 294 N
For minimum pressure, it will be at maximum area.
Max area will be at biggest dimensions.
Max area = 0.4 × 1.5 = 0.6 m²
P_min = 294/0.6
P_min = 490 N/m²
Similarly, maximum pressure will be at minimum area.
Minimum area = 0.1 × 0.4 = 0.04 m²
P_max = 294/0.04
P_max = 7350 N/m²
