There is a kind of brick with thickness of 5cm and density of 2.5 × 10 & sup3; kg / M & sup3. When it is laid flat on a horizontal plane, the pressure on the ground is? There is a kind of brick with thickness of 5cm and density of 2.5 × 10 & sup3; kg / M & sup3; 1. What is the pressure on the ground when it is placed horizontally? 2. This kind of brick is used to build 18m high wall, and the cement slurry with density of 2.0 × 10 & sup3; kg / M & sup3; is filled between the upper and lower layers and the gap between the wall base. The thickness of the cement slurry is known to be 1cm, so what is the pressure on the ground?

The pressure of regular solid can be calculated by liquid formula
1. P = pGH = 2.5 × 10 & sup3; kg / M & sup3; * 10N / kg * 5 times the - 4th power of ten
=10pa
2. The height of each floor is 6cm
The number of layers of cement brick is 1800cm / 6cm = 300
Then follow the train of thought
