我们知道，ｐ＝ρｇｈ是静止液体内部压强的计算公式．那么，能不能运用这个公式来计算固体的压强呢？下面我们来看这样一道题目：已知长为ａ，宽为ｂ，高为ｈ，密度为ρ的长方体放在水平面上，求它对水平面的压强ｐ．解析　　　　物体对水平面的压力等于其重力，可见，长方体 We know that p = ρgh is the formula for calculating the internal pressure of a stationary liquid. So, can you use this formula to calculate the solid pressure? Here we look at such a topic: Known for a length of b, a width of h, a height of h, a cuboid with a density of ρ is placed on the horizontal plane, and its pressure on the horizontal plane is p. The pressure of the object on the horizontal plane is equal to its gravity, visible, rectangular
