The length, width and height of a brick are 20cm, 10cm and 5cm respectively, and its density is 1500kg / m3. Put it on the horizontal ground and calculate its impact on the ground The best calculation process reference answer: maximum 3000 minimum 750

The length, width and height of a brick are 20cm, 10cm and 5cm respectively, and its density is 1500kg / m3. Put it on the horizontal ground and calculate its impact on the ground The best calculation process reference answer: maximum 3000 minimum 750

Pressure = 1500 * 20 * 10 * 5 * 10 * 10 ^ (- 6) = 15N;
The maximum pressure is 15 / 50 * 10 ^ (- 4) = 3000pa;
The minimum pressure is 15 / 20 * 10 * 10 ^ (- 4) = 750pa;
