tend to move the body upwards. Let us imagine a cube immersed in a mass of water (fig. 84), and thatfour of its edges are vertical. The pressures upon the four vertical faces beingclearly in equilibrium, we need only consider the pressures exerted on thehorizontal faces A and B. The first is… … Fig. 84. face itself, and whose height is BD (100). The cube, therefore, is urgedupwards by a force equal to the difference between these two pressures,which latter is manifestly equal to the weight of a column of water havingthe same base and the same height as this cube. Consequently, this…
